  • Running router as virtual machine, can it be realible ?

    - by Kr1stian
    Hi all Does anyone here run their routing through virtual machine, have virtual machine setup as main router/getaway etc ? If yes, how many clients are using this kind of setup ? For those who are wondering why I'm asking this. I got assignment for my internship to create all in one "box" which would do routing and be IP PBX in one time ( only open source solutions can be used, expect RouterOS). The routing part is currently done through RouterOS and for VoIP they want to use sipXecs. RouterOS supports virtualization through KVM, but RouterOS itself only supports 2GB of memory ( and wont support more in near future). sipXecs needs allot more than 2GB. I told them that we could solve this problem by putting RouterOS as virtual machine to 64bit hostOS ( e.g. CentOS), and other virtual machine would run sipXecs. By that we would be able to use whole memory. But they told me that it's to risky to do something like that and that they need something with "enterprise stability/reliability". I told them that we could make redundant image of each VM which would automatically start if one VM stop's working, but I was told the same thing. So this is why I asked those question above, to see if I really suggested something that's not good to do, or maybe this is something completely normal and it can be done with "enterprise stability/reliability" :) Thank you for answers, Kristian

  • 2.6.9 Kernel on virtual server (non upgradable) - any expected problems?

    - by chris_l
    Hi, I'm considering to rent a virtual server (for me personally). The product I'm currently looking at offers IMO fair pricing, very good hardware etc. The only problem is, that I won't be able to do an upgrade to a newer kernel than 2.6.9 (running Debian Etch). Also, I can't install my own kernel modules. (The server runs with Virtuozzo, so as far as I understand it, it just does some chroot instead of a real virtualization (?)) I want to run GlassFish, Postgres, Subversion, Trac and maybe some other things on it. It will also have to employ a firewall, and provide OpenSSL for https. Ideally, it would also be able to do AIO (asynchronous IO), which could speed up some server I/O. Should I expect problems with that old kernel version, in conjunction with the software I want to install (I'd like to use current versions of the software)? One thing I already found out, is that you can't do everything with iptables, since some kernel modules are missing/things are not build into the kernel. GlassFish v3 appears to run fine at first glance. I was able to test the server for a few hours. Installing my whole setup wasn't feasible in that time, but what I can say is, that it's amazingly fast for an entry-level vserver, especially hard disk and network performance (averaging at ca. 400MBit/s). So if the kernel won't be a problem, I'd really like to take it. Thanks, Chris PS Exact kernel version: 2.6.9-023stab051.3-smp

  • VM automatic provisioning advice

    - by jdgregson
    In my lab we have 24 workstations, each with five technician-maintained virtual machines set up in VMware Workstation. These provide a lot of management overhead, as we have to update them as well as the host operating systems every three months (the start of the next quarter), which adds up to 144 systems to update instead of just 24. Whenever we need to reimage the hosts, the VMs add another 130GB to each image, which is over 3TB of extra data to send over the network, and a lot more time to apply each image, and then we still have to boot all 120 VMs and assign them a unique IP Address and host names. We would like to get the VMs off the hosts and onto a server, but after looking around for a few days, I still don't know where to begin looking for a solution. There may be a better way to do this, but in my mind, the ideal solution would be to replace the VMs on the host machines with five Thin Client operating systems, each configured to connect to a server and be sent or connected to a unique virtual machine. We can't have 120 VMs running on the server all the time, so the server would have to create a copy of the VM from a template whenever a student tries to boot one, and destroy the VM after the student is finished with it. If there is another client application that has to be installed on the hosts that would be fine, the only reason I'd like to keep them in VMware Workstation is because students already know to look there for the VMs when they need to use them. What, if any, virtualization software will allow this? Is there some other solution I'm not seeing?

  • Determining failing sectors on portable flash memory

    - by Faxwell Mingleton
    I'm trying to write a program that will detect signs of failure for portable flash memory devices (thumb drives, etc). I have seen tools in the past that are able to detect failing sectors and other kinds of trouble on conventional mechanical hard drives, but I fear that flash memory does not have the same kind of predictable low-level access to the hardware due to the internal workings of the storage. Things like wear-leveling and other block-remapping techniques (to skip over 'dead' sectors?) lead me to believe that determining if a flash drive is failing will be difficult at best, if not impossible (short of having constant read failures and device unmounts). Flash drives at their end-of-life should be easy to detect (constant CRC discrepancies during reads and all-out failure). But what about drives that might be failing early? Are there any tell-tale signs like slower throughput speeds that might indicate a flash drive is going to fail much sooner than normal? Along the lines of detecting potentially bad blocks, I had considered attempting random reads/writes to a file close to or exactly the size of the entire volume, but even then is it possible that the drive might report sizes under its maximum capacity to account for 'dead' blocks? In short, is there any way to circumvent or at least detect (algorithmically or otherwise) the use of block-remapping or other life extension techniques for flash memory? Let me end this question by expressing my uncertainty as to whether or not this belongs on serverfault.com . This is definitely a hardware-related question, but I also desire a software solution - preferably one that I can program myself. If this question is misplaced, I will be happy to migrate it to serverfault - but I do need a programming solution. Please let me know if you need clarification :) Thanks!

  • DIY a simple .inf on an existing .sys?

    - by Stijn Sanders
    In continuation of attempting to get an old Digi ST-1032 working on a new server, we've downgraded a server to Windows 2000 in an attempt to use the NT4 drivers. And it works, the old software setup works, finds the device on the SCSI bus, and connects the 32 ports to COM3..COM34 or any other set using the port remapper tool. The minor issue that remains is that Plug-and-Play still detects this device over SCSI and tries to wizard you into selecting a driver for it. Which doesn't exists (Digi Intl support confirms this device is so old, a 2000 or XP driver was never made). The exact name displayed is "DigiIntl ST-1032 SCSI Net Device" (Oddly enough, two devices get detected with this name, on two neighbouring LUN's, could one be the built-in terminator?) Is there a way to concoct a simple .inf that would (re-)register the existing sts.sys that appears to get registered by the (old) installer of the driver software?

  • Force RAID to read "exiled" disk?

    - by user197015
    We have a RAID 6 array (Infortrend EonStor DS S16F) that recently had two disks fail. Immediately prior to replacing these two disks, a third, good, disk was accidentally ejected from the array. After reinserting this disk it is marked as "exiled" by the array's firmware, and so even after replacing the two failed disks with new ones the array refuses to rebuild the logical volume and remains inaccessible. Since the temporarily-ejected disk is still functional and nothing has been written to the array since it was ejected, it seems that it should theoretically be possible to recover all the data on the array, but how can we convince the array to use the data from the "exiled" disk? Thanks for any help or advice you can offer.

  • Differences between KVR16N11H/8 and KVR16N11/8 memory except for height?

    - by rzetterberg
    I accidentally ordered KVR16N11/8 instead of KVR16N11H/8 and I'm wondering if I'm going to have compability issues with my Intel DP67DE motherboard. When searching for compatible RAM on Kingstons site for that motherboard the KVR16N11H/8 RAM was one of the compatible ones. The KVR16N11/8 did not show up as compatible for that motherboard. The only difference I can see is that they have different physical height, or am I missing something?

  • Sony PCG-252L white screen help

    - by rm
    I have a PCG-252L All-in-one desktop. Last week it downloaded some updates, restarted, and even since then is shows nothing but a white screen. I can hear the beeps on startup, screen changes from white to black a couple of times, and then stays white. There's no VGA or HDMI port on the computer, so I can't plug it into the external monitor. Any ideas?

  • HD Tune warning for "Reallocated Event Count" with a new/unused drive. How serious is that?

    - by Developer Art
    I've just looked at the health status of my old 2,5 inch 500 Gb Fujitsu drive with a popular "HD Tune" utility. It shows a warning for the "Reallocated Event Count" property. How serious is that? The thing is that the drive is practically new. I pulled it out of a new laptop over a year ago and never used it since. Right now it only has 53 "Power On" hours which sounds about right since I only had it running a few evenings overnight before switching it for something more performant. Does this warning indicate that the drive is likely to fail some time in the future? I'm somewhat perplexed since the drive is effectively unused. What is more, I have arranged with somebody to buy off this drive since I don't really need. It is 12,5 mm thick (with 3 plates) meaning it doesn't fit into an external enclosure which makes it quite useless to me. Can I give away the drive without having it on my conscience or better cancel the deal? In other words, can the drive be used safely for years to come or better throw it away? I'm running a sector test now to see if there are any real problems. Will post the results as soon as they're available.

  • Graphics card not working but integrated graphics is working

    - by Dustin Martin
    I have a PCIe Geforce 6600 that I've been using in my PC for a couple years now without problems. Recently though I've not been using the PC and had it unplugged. When I when to use it again I accidentally plugged in the monitor to the VGA port for the integrated graphics instead of the 6600 card VGA port and began using it again (I'm currently running Windows 7). I then realized that I had the monitor plugged in wrong and switched the monitor to the 6600 port. Unfortunately I cannot get it to work. When the monitor is plugged in to the 6600 port the monitor will not display anything; not when booting up or in Windows (so I don’t believe the problem is Windows related). I've even tried booting a live CD for Ubuntu to see if that will recognize the card but no luck. Somehow it seems I need to "turn off" the integrated graphics and instruct the PC to use the 6600 card but I'm at a loss for how to do that. I looked high and low in the BIOS for a setting to do this but cannot find anything at all. I have a MSI motherboard and AMI Bios. Any ideas?

  • HP D530 Startup Error: 512 - Chassis Fan Not Detected

    - by lyrikles
    I'm using the HP D530 Motherboard/CPU that I installed in a new case with a 600W PSU. There was a problem with the onboard chassis fan connector (3-wire) not supplying sufficient power to the chassis fan indicated by the fan spinning very slowly, but I never experienced the "512 Error" at boot. Also, the same fan works perfectly connected directly to the PSU. I disconnected it since I already have plenty of fans connected via the PSU directly. Since then, on startup, I get the error: "512 - Chassis Fan Not Detected" and am asked to "Press F1 to continue". This gets quite annoying since I use this machine remotely (w/ FreeNAS). What could be causing the onboard fan connector to not be giving enough power? If this is unable to be corrected, how can I make the BIOS think there's a chassis fan plugged in without actually plugging a fan into the onboard connector? Would it be possible to jumper the pins without damaging the motherboard or PSU? Thanks,Erik

  • BIOS interrupts, privilege levels and paging

    - by Jack
    Hi, I was learning about Intel 8086-80486 CPUs and their interactions with HW. But I still don´t understand it quite well. Please, help me fill blank spots. First, I know that CPU communicates with HW using BIOS interrupts. But, what really happens in PC, when I call some INT instruction? I know that according the interrupt table some instructions begin to execute, but how by executing some instructions can BIOS recognize what I want to do? Becouse as far as I know, CPU has no extra communication channel with BIOS, it can only adress memory and receive data. So how can I instruct BIOS to do something, when I can only address RAM? Next thing I don't understand is about privilege levels. I know about ring model, and access rights, but how does the CPU know which privilege level has executed an instruction? I think that these privileges apply only when intruction is trying to address memory, but how does an application get its privilege level? I mean I know its level 3, but how is it set? And last thing, I know that paging is address scheme that is used to support aplication-transparent virtual memory, or swapping, but I could not find any information about how paging is tied with protected mode. Like if paging is like next mode independent of protected mode, or its somehow implemented within protected mode. And if it is implemented in protected mode, isn´t it too slow, to first address application space, then offset, and then paging folder, page and offset once again?

  • What does the condition "new pull" mean?

    - by Nathan DeWitt
    I'm looking for a hard drive, and some of the conditions are listed as "New Pull" or "System Pull". I figure the System Pull means "taken from a computer and now sold separately" but what does New Pull mean? Does this mean it was assembled and never used? Or maybe it has been freshly pulled from a used machine?

  • NetBSD Networking

    - by Mike
    Hello, everyone! I have an old Toshiba Satellite 4015CDT, with Pentium II MMX, 32MB RAM, 4GB HDD. It also has one USB 1.0 port, parallel and serial ports, a 3.5" floppy drive and a CD-ROM drive (probably almost dead). I've installed NetBSD on this machine (full install) and now I want to connect it to the Internet. Although it has one PCMCIA modem card in it, it is obviously not an option. I've narrowed down my available options to the following: Connect a USB wireless adapter. I have a Realtek RTL8192 adapter, but although the system gives me the device's name (through dmesg) it fails to recognize it as a network adapter. Connect the laptop to another machine through a serial connection, so that the other machine will serve as a bridge to the Internet. Here is the page from the NetBSD documentation on serial connections. Unfortunately, I was not able to find anything on bridging there. I would very much appreciate your suggestions on the topic. Thanks in advance.

  • Partitioning recommendations for a Proxmox VM Server (OpenVZ)

    - by luison
    We are new to virtualization and we are planning to turn our online server into a virualized one, mainly for maintenance, backup and recovery improvements. Initially we would only have one real virtual system with load plus 1-3 copys for testing and recovering and maybe a small centralized syslog virtual machine. We would like, if possible the host machine to include an iptables plus rsync to back up to other machines and some other global security systems. Due to this and the offerings of our hosting supplier we are mainly considering Proxmox for its simplicity (we like the idea of its web admin panel) and as I also understand that the container approach of OpenVMZ systems may fit well resource wise with our setup. The base system comes with debian so we can personalise it to our requirements. Proxmox installations default installs an LVM partition for the VMs. Our doubts are with the fact of what would be the best partition structure for this considering that: we would like to have a mirror of the root partition we could boot from if required (our provider supports booting the system from another partition via control panel) we ideally would like to have a partition that could be shared among the VM systems. We still don't know if this is possible directly with OpenVMZ containers, otherwise we are considering doing this by sharing it via NFS on the host machine. we want to use the backup system available on the proxmox host administrator to programme VMs backups and then rsync it to another machine. With this based on a Linux Raid of aprox (750Gb) we are considering something like: ext3_1/ - (20Gb) ext3_2/bak_root - (20Gb) mostly unmounted, root partition sync LVM_1 /var/lib/vz - (390Gb) partition for virtual images LVM_2 /shared_data - (30Gb) LVM_3 /backups - (300Gb) where all backups would be allocated Our initial tests with Proxmox seem to have issues with snapshots backups like this, perhaps caused by the fact that they can not be done to another LVM partition (error: command 'lvcreate --size 1024M --snapshot --name vzsnap-ns204084.XXX.net-0 /dev/pve/LV' failed with exit code 5) in which case we might have to use a standart ext3 partition (but unsure if we can do this with the 4 primary partition limitations). Does this makes more or less sense? Would it be mad to for example write VMs /var/logs to a NFS mounted partition (on the host system)? Are their any other easier ways to mount host system partitions (or folders) to the VMs?

  • Upgrading a PERC h310 to a PERC H710 mini RAID controller on a Dell R620

    - by Gregg Leventhal
    I have an ESXi 5.0 Free license host using an internal Datastore (RAID 5, 5 Disk) that was configured with a Dell PERC h310 RAID controller. The disk performance was very poor, so I upgraded to the PERC H710 Mini. The IT Tech installed the controller and powered the host back on. I had to rescan the controller and the datastore appeared. Should any settings be changed in the RAID BIOS, or should the default settings be sufficient? Is they anything to be aware of when performing this type of upgrade in order to achieve the maximum performance?

  • Buying replacement Macbook Pro Battery - Genuine vs. eBay

    - by Nicolas Webb
    I'm looking to replace my Macbook Pro's battery (15", last model before the Unibody). It's currently at 55% capacity (as reported in System Information and Battery Health Monitor). I've reset the SMC firmware, calibrated the battery, and it's just not lasting that long anymore. I've seen some genuine replacements that are "pulls" (pulled from used computers) that are rated at least 90% capacity (iFixit, MacSales). I've also seen a variety of batteries on eBay that look more like clones than genuine batteries, but are new. A new battery from Apple is $129, and when I brought my laptop in they ran the Battery test and said if I bought the battery right then they'd give me a discount (around $100). Anyone out there used one of these "OEM Compatible" batteries? Fit/finish good? (I don't want a funky color or a corner that sticks out.) Or, should I just suck it up and get the genuine replacement (for about twice the price)?

  • Dell Poweredge 2650 RAM Upgrade

    - by Vik
    Hi, I bought an old Dell Poweredge 2650 off ebay to use as a dev server, but I need to get more RAM for it. From what I understand there were 2 versions of the 2650 released, with the older version only supporting PC1600 RAM (200MHz) and the 2nd version supporting PC2400. Unfortunately Dell thought it wasn't necessary to label their servers as such so I can't tell what version I have. Does anyone know if there is a way to tell without buying and testing RAM in the server?
