  • VirtualBox: Can't get Bridged Networking to work (Win7 host)

    - by MikeTheTall
    I'm trying to set up a virtual LAMP server, including sharing files between the guest OS (Ubuntu Server) and the host OS (Windows 7) using samba. I think my problem is that I can't get Bridged (or Host-Only) networking to work in VirtualBox. I can boot the Linux VM just fine with NAT, but then can't access any services on it directly (except after port-forwarding port 80)(my understanding is that port-forwarding works because I'm not running a web server on the host OS, and therefore it can forward traffic to the unused port 80). I don't think that port-forwarding samba traffic (from the host to the guest) will work since I think that the host OS is using those ports. When I turn off NAT and turn bridged networking on I get an error. The VM fails to boot, with a dialog popping up (title: VirtualBox - Error) that says "Failed to open a session for the virtual machine UbuntuServer. Configuration error: Failed to get MAC address (VERR_CFGM_VALUE_NOT_FOUND). I'm hoping that once this is resolved then samba will work ok :) Any advice on this would be great (how to fix it would be wonderful, next steps for troubleshooting would be great, too :) )

  • NVIDIA GeForce GT750M drivers for Ubuntu 13.10 on iMac

    - by Eugene B
    I have just got a new iMac 14.3 with 21.5' display. It has Intel i7 processor and NVIDIA GeForce GT750M graphics card with GPU (Device ID: 0x00fe9). I have installed Ubuntu 13.10 on it (dual boot with refit). Everything works fine apart from graphics. It is clear that graphics' not accelerated, and there are no drivers suggested in the "Additional drivers" section. I have tried to Install nvidia drivers from the repository. Download nvidia drivers and install them manually. Follow instructions here. Follow instructions here. Follow instructions here. Install bumblebee. Play around with xorg.conf file. Blacklist nouveau. As you may guess, nothing worked. The weirdest thing is, that when I boot from a LiveCD, it picks up screen resolution and all the rest correctly, though when I install the system to my Hard Drive it clearly does not have proper drivers. Does anyone have any suggestion what to do?

  • Converting An Older VMWare Image to ESXi

    - by Bart Silverstrim
    I have just installed VMWare ESXi and imported one physical machine without issue and one virtual machine, from an older version of VMWare Server on a Linux system, to it without issue. But I have another machine (Windows XP), virtual running on the VMWare Server, that I can't get the Converter to work with. Converter runs, says everything is fine, but when I go to the ESXi VSphere manager and hit the button to power up that vm, the console stays black with a blinking cursor and the processor for that VM spikes 100% and stays there. An event log item in VSphere warns something about activation issues with Windows. Has anyone else run into this issue before? Is it something with the disk controller? I copied the folder with the VM directly to the storage drive on ESXi hoping to create a new machine and point the data store to that folder or at least that drive image; nope, something about not using an IDE controller (must be something with the older format). In short, converter is doing something that particular machine doesn't like, and I can't find a way to simply open that hard disk image or convert it unless someone else has seen this. I try attaching a bootable CD image for disk repair to see if it can check the hard drive but I can't seem to get the console to boot from it...either too slow on the button or it just isn't able to easily boot from a virtual drive image (.iso). Any suggestions or help?

  • Will these instructions work when turning of journaling on a n ext4 SSD?

    - by snowlord
    I have an Acer Aspire One with an SSD for storage. I recently installed Ubuntu on it and chose ext4 for my filesystem. Then I read that journaling on an SSD isn't the best idea, so I will try to disable journaling and I have found these intstructions (from http://fenidik.blogspot.com/2010/03/ext4-disable-journal.html): # Create ext4 fs on /dev/sda10 disk mkfs.ext4 /dev/sda10 # Enable writeback mode. This mode will typically provide the best ext4 performance. tune2fs -o journal_data_writeback /dev/sda10 # Delete has_journal option tune2fs -O ^has_journal /dev/sda10 # Required fsck e2fsck -f /dev/sda10 # Check fs options dumpe2fs /dev/sda10 |more For more performance add fstab opions: data=writeback,noatime,nodiratime i.e: /dev/sda10 /opt ext4 defaults,data=writeback,noatime,nodiratime 0 0 I will use them on my boot partition. Are there any particularly bad parts here, or are there any missing steps? Will my boot partition be fit for being on an SSD after this? Or should I consider switching to ext2, or even reinstall it all and choose ext2 at partitioning time (I'd rather not though, since I've configured quite some stuff already)?

  • linux hardware raid 10 / lvm / virtual machine partition alignment and filesystem optimization

    - by Jason Ward
    I've been reading everything I can find about partition alignment and filesystem optimization (ext4 and xfs) but still don't know enough to be confident in setting up my current configuration. My remaining confusion comes from the LVM layer and if I should use raid parameters on the filesystem in guest os'es. My main questions are: When I use 'pvcreate --dataalignment' do I use the stripe-width as calculated for a filesystem on RAID (128kB for ext4 in my situation), the Stripe size of the RAID set (256kB), something else altogether, or do I not need this? When I create ext2/3/4 or xfs filesystems in guests on the Logical Volumes, should I add the settings for the underlying RAID (e.g. mkfs.ext4 -b 4096 -E stride=64,stripe-width=128)? Does anyone see any glaring errors in my set up below? I'm running some benchmarks now but haven't done enough to start comparing results. I have four drives in RAID 10 on a 3ware 9750-4i controller (more details on the settings below) giving me a 6.0TB device at /dev/sda. Here is my partition table: Model: LSI 9750-4i DISK (scsi) Disk /dev/sda: 5722024MiB Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags 1 1.00MiB 257MiB 256MiB ext4 BOOTPART boot 2 257MiB 4353MiB 4096MiB linux-swap(v1) 3 4353MiB 266497MiB 262144MiB ext4 4 266497MiB 4460801MiB 4194304MiB Partition 1 is to be the /boot partition for my xen host. Partition 2 is swap. Partition 3 is to be the root (/) for my xen host. Partition 4 is to be (the only) physical volume to be used by LVM (for those who are counting, I left about 1.2TB unallocated for now) For my Xen guests, I usually create a Logical Volume of the needed size and present it to the guests for them to partition as needed. I know there are other ways of handling that but this method works best for my situation. Here's the hardware of interest on my CentOS 6.3 Xen Host: 4x Seagate Barracuda 3TB ST3000DM001 Drives (sector size: 512 logical/4096 physical) 3ware 9750-4i w/BBU (sector size reported: 512 logical/512 physical) All four drives make up a RAID 10 array. Stripe: 256kB Write Cache enabled Read Cache: intelligent StoreSave: Balance Thanks!

  • Building a PC, advice on SSD/Hybrid Hard Drives

    - by Jamie Hartnoll
    I am looking at building a new PC, it's mainly for office (graphics heavy) use and programming. Looking for good performance with opening and closing programs and files as well as a fast boot. I plan to have 3 primary hard drives Windows 7 Programs (photoshop etc) Current Files (There'll also be a large storage capacity back up drive, but this will be the Seagate drive I already have.) So, my question is, looking at standard "old fashioned" hard drives and SSD drives, obviously there's a massive price difference. I have been looking at drives like this: http://www.ebuyer.com/268693-corsair-120gb-force-3-ssd-cssd-f120gb3-bk-cssd-f120gb3-bk and this: http://www.ebuyer.com/321969-momentus-xt-750gb-sata-2-5in-7200rpm-hybrid-8gb-ssd-in-st750lx003 Having no experience of using either I don't know what's the most efficient thing to go for. Clearly the SSD will have better performance, but: If, for example, I had an SSD for Windows (say about 100gB), that would clearly give me the boot speed I want, then I guess my real questions are: If I were to buy one more SSD, would it give the greatest improvement on standard performance if used to store programs, or currently used files? Given that the OS is on an SSD, should I not bother with the 3 drives and instead, partition that Hybrid drive to store programs and currently used files on it? Obviously, option two is cheaper and option one could cause me storage issues, but that's when I can dump files I am not currently using onto another drive. Any, I am open to suggestions... so what do you suggest?!

  • Windows XP only loads in VGA mode, and crashes when raising resolution

    - by Harel
    My kid's computer (Windows XP, SP3) started to (what appears to be) crash on boot. It will only boot in Safe or VGA mode, and if I try to raise the resolution from 640x480 it just reboots itself, and a error appears in the Event Log. When it loads up not in VGA mode, the monitor shuts off just after the windows logo is shown. It seems like windows is actually running but I can't see anything on screen (monitor is off for lack of signal). Nothing was installed recently that I know of, short of the usual windows updates. Thanks, Harel Below is the event log error: Event Type: Error Event Source: System Error Event Category: (102) Event ID: 1003 Date: 15/04/2012 Time: 16:27:11 User: N/A Computer: ----- Description: Error code 1000008e, parameter1 c0000005, parameter2 f745b0bf, parameter3 ede24f98, parameter4 00000000.

  • Setting up Windows network on Xen

    - by samyboy
    I'm trying to install a Windows XP server in a Xen environment. The OS is booting fine. Unfortunately I can't figure out how to set up the network settings. Dom0 is a Debian Lenny currently hosting around 10 Linux virtual servers. Windows tells me I have a "limited connection". It can't get any DHCP response, nor access other hosts in the network Here is the Xen's client config file: kernel = '/usr/lib/xen-3.2-1/boot/hvmloader' builder = 'hvm' memory = '1024' device_model='/usr/lib/xen-3.2-1/bin/qemu-dm' acpi=1 apic=1 pae=1 vcpus=1 name = 'winexchange' # Disks disk = [ 'phy:/dev/wnghosts/exchange-disk,ioemu:hda,w', 'file:/mnt/freespace/ISO/DVD1_Installation.iso,ioemu:hdc:cdrom,r' ] # Networking vif = [ 'mac=00:16:3E:0A:D0:1B, type=ioemu, bridge=xenbr0'] # video stdvga=0 serial='pty' ne2000=0 # Behaviour boot='c' sdl=0 # VNC vfb = [ 'type=vnc' ] vnc=1 vncdisplay=1 vncunused=1 usbdevice='tablet' Server config (/etc/xen/xend-config.sxp) (network-script network-bridge) (network-script network-dummy) (vif-script vif-bridge) (dom0-min-mem 512) (dom0-cpus 0) (vnc-listen '0.0.0.0') Since I use Debian I had to create a link like this: /etc/xen/qemu-ifup - /etc/xen/scripts/qemu-ifup What did I do wrong?

  • XP Pro freezes on welcome screen

    - by Peter B
    I have a problem that sounds much the same as http://superuser.com/questions/83101/how-to-diagnose-a-freeze-on-startup-in-windows-xp About every 2nd or 3rd boot, XP-Pro freezes on the Welcome page (the one showing the user name icons). The mouse moves the cursor OK, but clicking on an icon does nothing, and neither does any keystroke. If you press too many keys there is a beep and after that the mouse won't move the cursor anymore. The work-around is always to reboot into Safe mode and request a CHKDSK /R After this, the next boot is fine. There are no related entries in the Event log when the problem occurs. The only two entries are: "Microsoft (R) Windows (R) 5.01. 2600 Service Pack 3 Multiprocessor Free." "The Event log service was started." Update 1: Many thanks for that but I found no problems with any diagnostics I have run. But, I have managed to locate, and code round, the source of the problem - which is with whatever processing goes on behind the XP Welcome (as opposed to "classic") login screen. Unfortunately, having classic login means you don't get the useful Fast User Switching (FUS) login/switch mode. So, to retain this, my fix is: Add a Windows shutdown script (using gpedit.msc) to force "classic" mode for the first logon after next XP startup, by running: reg add "hklm\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon" /v LogonType /t REG_DWORD /d 0 /f Add a Scheduled Task to run at User Logon that enables Welcome screen (and hence FUS) by running the same command with 1 instead of 0 after the /d flag. The task is run as a privileged user (who can run "reg add").

  • SSD seems dead after wakeup from Windows Sleep, BIOS stalls but doesn't find it anymore

    - by Abel
    The morning, the following scary scenario happened: I woke up my Windows system Typed in my username and got an error (something like "could not load security xxx", but unsure of exact wording) System auto-restarted after cliking OK It didn't boot up anymore to the SSD with Windows 7 OS (I have another disk I can boot to, but that doesn't see the disk either). Obviously, this happened right after I instantiated a backup procedure, which hasn't succeeded either. The BIOS can't find the drive when I connect to SATA. And it can't find the drive when I connect it to SAS. I have a Dell Workstation T7400, most recent BIOS (version A06), version of SAS Host Bus Adapter BIOS (HBA) is MPTBIOS 6.14.10.00 (2007.09.29) from LSI Logic Corp. Other findings: When connecting to SATA, the DELL Logo screen stays really long (5 minutes) and then at the end of POST it says that a drive is not found When connecting to SAS, the SAS HBA initializing phase takes long (2 minutes, against normally 15 seconds) When running Dell Diagnostics, it doesn't finish and gives the error Exception occurred in module MPCACHE.MDM file "IOAPICSP.ASM" line 1645. I contacted Dell. On their advice I tried different slots and different cables to no avail. I use an APIC battery power, spikes in the power are thus unlikely. My conclusion so far: the disk is dead. I need this disk very badly because it contains the last few days of important development of which not all code was checked in the moment this happened. Are there any ways to recover dead SSD drives? The drive is a new X25-M G2 160GB model SSDSA2M160G2GC 2.5" in an extension bay and has been running without issues for 3 months on SAS.

  • Grub hangs at "Starting up ..." when USB flash card reader is plugged in (on Ubuntu Hardy)

    - by Laurence Gonsalves
    I have a PC with Ubuntu Hardy installed. The machine boots fine unless my USB flash card reader (one of those N-in-1 readers by MediaGear) is plugged in at startup. If the reader is plugged in, the boot process proceeds as normal until it gets to the screen that says "Starting up ...". At that point it just hangs forever. To work around this I currently leave the reader unplugged when booting, and then plug it back in after I see that Ubuntu is actually starting. This is annoying though, especially when I reboot the machine (typically for updates), forget to unplug the reader, and walk away only to come back hours later to find the machine hung. My guess is that the presence of the reader is confusing Grub about where to find the kernel. The weird thing is that Grub is on the same drive as the kernel I want it to boot so clearly the drive is still readable even when the flash card reader is plugged in. Is there some way I can tell Grub to never go looking on the flash card reader?

  • What to do with a broken OS X install disc?

    - by slhck
    First things first: I don't appreciate software piracy and I really want to spend money on software that I use and that I work and make money with. I don't want this question closed just because I consider downloading software, I only want honest opinions and alternatives. Here we go: So I have my OS X Snow Leopard Upgrade DVD, but it's horribly scratched and won't boot anymore. It endlessly loads and at some point I have to force pull it out of the disc slot. How can I reset my Mac then? Can I take my original disk to an Apple Store and ask them for a replacement? Will they believe me, even if I don't have the receipt anymore? Would owning the original disk make it okay for me to look somewhere on the internet and download it? I don't even know if that will work without hassles. Could I try to read the disk to an image with some error correction methods? Maybe during boot it can't read some files, but some other program can? Is there any other way of resetting the Mac? Mine's now over 3 years old an I seem to have misplaced my original discs that had 10.4 on it. Or should I just buy a new 10.6 upgrade disk? (Which is not really what I want to do) Answers and opinions would be much appreciated.

  • systemd: enabling cherokee service as a `unit file`

    - by Calvin Cheng
    So I am learning how to use systemd to initialize my services automatically on server reboot. So of course, I first make sure I have systemd and some optional systemd related packages installed. pacman -S systemd initscripts-systemd Installation seems to go well and checking, I can see that systemd and its dependency libsystemd are installed. And the optional package initscripts-systemd is also installed:- [root@li280-195 ~]# pacman -Ss systemd extra/libsystemd 44-5 [installed] systemd client libraries extra/systemd 44-5 [installed] system and service manager extra/systemd-sysvcompat 2-2 sysvinit compat symlinks for systemd community/initscripts-systemd 20120412-1 [installed] Arch specific systemd initialization/bootup scripts for systemd community/systemd-arch-units 20120412-2 Arch specific Systemd unit files Next, I ensure that systemd is loaded up when my server reboots, via grub in grub's /boot/grub/menu.lst file like this:- kernel /boot/vmlinuz root=/dev/xvda ro init=/bin/systemd Rebooting my server to check, all loads up well and I can check that systemd is operational via:- systemctl list-unit-files However, I don't see my cherokee initialization script (which is simply created at /etc/rc.d/cherokee when I installed cherokee earlier via pacman -S cherokee) being listed as one of my unit files. So the question is, how do I do that? How do I put my cherokee initialization script under systemd's control?

With a Linux distro I used this: virt-install -n debian -r 1024 --vcpus=1 --accelerate -v --disk /var/kvm/installation-disks/debian.img,size=6--nographics --network=bridge:br0,model=ne2k_pci,mac=52:54:00:66:68:09 -l http://ftp.de.debian.org/debian/dists/squeeze/main/installer-amd64/current/images/ -x console=ttyS0,115200 This loads the installer directly from the online mirror. With Fedora I used this mirror: http://www.nic.funet.fi/pub/mirrors/fedora.redhat.com/pub/fedora/linux/releases/16/Fedora/x86_64/os/ Are there such mirrors for freebsd or openbsd? The reason I want direct installable ftp/http mirrors is because I can access my physical server only via ssh, and it doesn't have a X server or a window manager to give me a VNC GUI. When I tried installing centos 6 with an online mirror I was able to finish the installation via serial console, but after I rebooted it, the serial console never worked for me. I tried everything possible---editing menu.lst, inttab and securtty files. Fedora 16 booted fine from serial console, but got stuck when it loaded anaconda installer. I tried editing freebsd iso installation media by adding serial console option to boot option. And installation was successful. But couldn't boot into it becuase it wasn't giving console acess. I couldn't edit any files as ufs partition cannot be loaded with write access on my Ubuntu server 10.04. Only debian squeeze worked well, it worked for me even without editing a single configuration file. I want to have CLI versions of fedora/centos and freebsd/openbsd. But, looks like there isn't any hope for me to have them, as I have to depend on a serial console to do everything.

  • Is USB supported in safe mode on XP?

    - by Hugh Allen
    According Microsoft, "Universal Serial Bus Devices Do Not Work in Safe Mode" under XP. However, in my testing this is incorrect. USB keyboards, mice and flash drives seem to work fine in safe mode (I made sure the BIOS was not providing support). This makes sense because a failure of a standard input device would be, in Microsoft parlance, a "bad user experience". So, Is USB supported in safe mode on XP? If your answer is no (agreeing with Microsoft), please provide a test case, preferably in a virtual machine, where a standard HID keyboard or mouse fails. Please state hardware / BIOS / OS configuration. Note that you will need a PS/2 keyboard attached in addition to your USB device(s) in order to use the boot menu. Virtual machine software usually emulates a PS/2 keyboard. Alternatively, you could add the /safeboot switch to boot.ini. If your answer is yes, please provide a link to some supporting documentation (either from Microsoft or someone authoritative). Your answer might be "devices X, Y and Z are supported but nothing else", in which case also give a link.

  • Hyper-v on 2012R2 startup gen1 vm causes the host to freeze up

    - by sputnik
    I've searched a lot to resolve the following issue, but nothing helped me. My problem is, that starting up a first-gen vm locks up the whole host. Only a hard reset helps. Second-gen vm starts and runs perfectly. The freezes happened on 3 different vms. FreeBSD, Ubuntu, Windows Server 2008R2, while Windows 8.1 on second gen config works perfectly. Im using this pc mainly as a workstation. No eventlog errors nor dumps are generated. My system: Windows Server 2012R2 FX-8350, non OC ASRock 870 Extreme R2 (Crappy board imho) 32GB DDR3 1866@1600 (My motherboard, against the "support" for 1866ram won't work with full speed) 120GB SSD 4.5TB Storage space device I dont think that its due to my system, because vmware workstation was running without problems. Did I forget to configure something? Any help is appreciated. P.S: Even deactivating C1E, C6, C&Q didnt work. P.P.S: With no virtual network adapter set, the system still locks up. Creating a first gen vm without any hdds and network and launching works. Attaching a boot dvd causes the host to freeze. The host freezes as the gen1 vm begins to boot, doesn't matter if from dvd or hdd

  • How to best convert a fully encrypted drive into a Virtual Machine?

    - by SiegeX
    I have a Windows XP laptop that uses GuardianEdge's Encryption Plus to fully encrypt the drive from bootup. What I would like to do is install a much larger (unencrypted) hard drive with Windows 7 on it and turn this fully encrypted drive into a Virtual Machine that can be ran in either Virtualbox or VMWare on the Windows 7 host. I've read many howto's that talk about using an imaging tool like Acronis True Image to image the drive then passing that through VMWare's VCenter Converter to turn it into a format that VMWare can understand. Unfortunately this seems to all far apart when you are dealing with a fully encrypted drive because Acronis cannot recognize the file system and attempts to do a sector-by-sector copy of the entire hard drive. This is extremely wasteful since the drive is 120GB but the file system is only using 10GB of that. Even if I were OK with going with an inefficient 120GB sector-by-sector copy, I'm not sure that this would even work under VMWare or Virtualbox. Unfortunately, the Guardian Edge boot-time login comes up only after the hard drive has been selected as the boot device; preventing me from being able to decrypt the drive prior to booting an Acronis True Image CD so that it can recognize the underlying file system. I'm sure I'm not the first person to want to do this but I am having a heck of a time finding solutions to this problem. All suggested/answers welcomed. Thanks

  • Want to use something like Citrix XenDesktop, Free Alternative?

    - by Chris
    I'm looking to go into IT, general office server management, and it looks like XenDesktop would be a awesome tool to use. If I get it right, you would store a central image of the OS you want to deploy (in an iso file) on the main server. Then use XenDesktop to pull that image down to the client, and it will then boot the OS inside of the virtual machine. Does it download the image of the OS and store it locally (like cloning the VM onto the client?) I'd love to find a free (possibly open source?) alternative to this, I keep on hearing about KVM in Linux and PXE booting a minimalistic OS to use remote KVMs.... Would that be what I'm looking for? Ideally, I'd like a system.. - That allows me to manage one central image for multiple clients (virtualized hardware) - Easily boot a thin client OS that connected to XenDesktop. Would those things be possible with some kind of free alternative? Some guidance would be greatly appreciated.

  • How to get an inactive RAID device working again?

    - by Jonik
    After booting, my RAID1 device (/dev/md_d0 *) sometimes goes in some funny state and I cannot mount it. * Originally I created /dev/md0 but it has somehow changed itself into /dev/md_d0. # mount /opt mount: wrong fs type, bad option, bad superblock on /dev/md_d0, missing codepage or helper program, or other error (could this be the IDE device where you in fact use ide-scsi so that sr0 or sda or so is needed?) In some cases useful info is found in syslog - try dmesg | tail or so The RAID device appears to be inactive somehow: # cat /proc/mdstat Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md_d0 : inactive sda4[0](S) 241095104 blocks # mdadm --detail /dev/md_d0 mdadm: md device /dev/md_d0 does not appear to be active. Question is, how to make active the device again (using mdmadm, I presume)? (Other times it's alright (active) after boot, and I can mount it manually without problems. But it still won't mount automatically even though I have it in /etc/fstab: /dev/md_d0 /opt ext4 defaults 0 0 So a bonus question: what should I do to make the RAID device automatically mount at /opt at boot time?) This is an Ubuntu 9.10 workstation. Background info about my RAID setup in this question.

  • Get Illegal Instruction error when booting Linux in VirtualBox, works fine when booted directly

    - by rkjnsn
    I have a computer on which I am dual booting Windows 7 and Gentoo Linux (both 64-bit). I want to be able to load up my Linux installation in a VM while I am booted into Windows. I have installed VirtualBox and followed the instructions for creating a raw disk VMDK. When I start the VM, Linux starts booting, but then fails with the following error when unlocking my root partition: truecrypt[441] trap invalid opcode ip:373615538e0 sp:3dd0e0dfb60 error:0 in libpixman-1.so.0[373614d6000+8d000] Everything works fine when I boot into Linux directly. What could cause an illegal instruction to be hit in libpixman only when booting in VirtualBox? Update: As a troubleshooting step, I recompiled pixman without "-march", and no longer get an illegal instruction error in that library. (The boot fails in the same spot with the same error in a different library, however.) How can I determine the specific opcode that isn't working in VirtualBox so I can disable it in my CFLAGS without having to disable all CPU-specific optimizations? I am still confused as to why there would be any user-mode instruction that would fail to work in a VM. Is this a known limitation? My CPU is an Intel Core i7 3720QM, and I have hardware virtualization support enabled.
