• raspberry pi for web programming/development

  - by Mark Dee

  I'm into web development and my machine (AMD Phenom II, 8G RAM) is running Ubuntu 13.04. I love my current setup but I kinda miss some of Windows software like MSOffice or Adobe suites, and running on Virtualbox doesn't feel as snappy for me.... So I'm thinking of buying a new cheap machine where I would install Linux and do my development work there and have my current machine run Windows. I just found this thing called Raspberry pi which is really cheap and requires 12v only (I think) which makes it good for downloading stuff overnight. So, does it make sense to buy Raspberry pi, make it my primary dev machine, Windows being the secondary (for Adobe and browser testing of course)? Basically, I want to know if Raspberry pi meets the following requirements: It should run ArchLinux Sublime Text 3 python ruby nginx nodejs Deluge or Transmission (well, maybe just those, no need for videos and music players)

• Dual-bootable Virtual Machine

  - by ojrac

  My work computer is a Linux desktop with a Windows 7 virtual machine for Visual Studio and IE testing. I'm very picky, and I don't want to configure two Windows installs... but I can't think of a way to do this without running afoul of Windows activation. I've already set up VirtualBox to run my VM off a physical hard drive, and grub isn't too hard to configure. But it'd be a waste of time without solving the activation problem. Is there any way I can boot into a single install of Windows as a virtual machine and on actual hardware without having to reactivate (until I'm eventually flagged as a pirate) every time I switch between the two? Is there any MS-endorsed way to use a single installed license with two sets of hardware?

• Video/Animated GIF advanced frame editor?

  - by meder

  What sort of application could I use for example if I had a 5 minute video or an animated GIF with 50 frames, and I wanted to basically Photoshop replace an object, say a person's head, with another image for all those 50 frames? Is there some sort of smart tool that can do this or do I have to edit every single frame by hand? I wouldn't mind there being a tool where I can paste the image in every frame automatically, and switch from frame to frame adjusting the position of it, I just need something efficient. I've tried using Photoshop's import video into image sequence and tried editing with the animation toolbar at the bottom, but it's not quite what I want. I don't care if it's free software or not, I'm primarily using Linux but I have VirtualBox Windows XP if there's an excellent application that's not available otherwise.

• dhclient configures /etc/resolv.conf with invalid entry

  - by kubal5003

  I'm trying to figure out why running dhclient on my interface sets /etc/resolv conf to the ip number of my gateway(router). This entry is invalid and each and every time causes inability to resolve any address. I would like to: stop dhclient from overwriting the /etc/resolv.conf or make dhclient write there the valid dns ip from my router More on the environment: I'm using virtual Debian Wheezy as a client system on Windows Seven x64. It is run by Virtualbox with networking mode set to bridged (all packets from debian are injected to my network interface on windows). If I manually configure the /etc/resolv.conf then everything works fine. Doing this on every boot is quite annoying.. PS I know I can write a script to do it for me, but this is not the solution I want. //edit router ip: 192.168.1.100 /etc/resolv.conf AFTER running dhclient eth0: "nameserver 192.168.1.100" what I would like the /etc/resolv.conf to look like: "nameserver 89.202.xxxx" (I don't have to provide the real ip do I? )

• Why is VMware vSphere Client hanging at the console?

  - by David

  When I use the vSphere Client (against an ESXi 4.1 server) it hangs a lot. It's always at the same place - using the console on a VM. The console stops responding - and a lot of times, the management window stops responding as well. The operating system won't close the window (as the application isn't responding) and requires a force close. I've had the console refuse to give up the mouse, and have had the console freeze with the cursor in the top left (before any VM software starts, maybe?). The environment is this: the system is a Dell laptop running Ubuntu 10.10 (Maverick) fully updated with VirtualBox OSE running Windows XP (also fully updated). The vSphere Client is running in the Windows XP VM. Got all that? How do I keep these hangs from happening? It is very aggravating. I'm still trying just to get the VM loaded with Ubuntu Server...

• How to Configure a vm on the same machine to do remote desktop [closed]

  - by Varun K

  I want to achieve following: (Note I'd like to get this done first of all with Win7 as both host and vm OS) Install Windows 7/xp/Windows 8 VM on Windows 7/Windows 8 host machine Configure it so that I can connect to it via remote desktop. This is because I use a screen reader software and audio output directly from VMs is not highly responsive. My software has a feature that it can connect to its copy on the remote machine (during rdp session) and then start receiving the text description which it translates into audio on the client (host in this case) machine. I want to know: Which VM software can let me do this – VMWare/Ms Virtual PC or VirtualBox If it is possible with every VM software, could you give an example of how to do this with anyone of these 3? Specifically, I know how to install Windows on VM (on both VMWare/Virtual PC), but don't really know how to configure a network such that I can remote into that VM from host OS. Hope it clarifies what I'm trying to achieve.

• Sensitive data in init scripts

  - by Steve Jorgensen

  I'm adapting some examples I've found by Googling to build an init script to run a VirtualBox OSE virtual machine as a daemon. I would like to specify a password for VNC access to the VM, and this must be given as an argument to the VBoxHeadless command. Conventionally, init scripts are readable by standard users, and this seems like a useful convention, but I also don't want the VNC password for this VM to be stored in easily accessible plain text. What's the most appropriate/conventional way to handle this kind of situation? Maybe put a root-readable supporting data file someplace, and have the init script load the value from there?

• Virtualizing OpenSolaris with physical disks

  - by Fionna Davids

  I currently have a OpenSolaris installation with a ~1Tb RaidZ volume made up of 3 500Gb hard drives. This is on commodity hardware (ASUS NVIDIA based board on Intel Core 2). I'm wondering whether anyone knows if XenServer or Oracle VM can be used to install 2009.06 and get given physical access to the three SATA drives so that I can continue to use the zpool and be able to use the Xen bits for other areas. I'm thinking of installing the JeOS version of OpenSolaris, have it manage just my ZFS volume and some other stuff for work(4GB), then have a Windows(2GB) and Linux(1GB) VM (theres 8Gb RAM on that box) virtualised for testing things. Currently I am using VirtualBox installed on OpenSolaris for the Windows and Linux testing but wondered if the above was a better alternative. Essentially, 3 Disks - OpenSolaris Guest VM, it loads the zpool and offers it to the other VMs via CIFS.

• UEFI - Linux Mint Boot from USB Doesn't work

  - by Joe Bennett

  I'm running Linux Mint (only OS other than in VirtualBox) and wanting to remove it. I've created a Live USB of Windows 8 using Windows 7 USB/DVD Download Tool - Yes, I know it says Windows 7 but I've been doing research and I am hearing from everywhere that it also works for Windows 8. The ISO was loaded on just fine (AFAIK) Computer came with Windows 8 pre-installed I have Safe boot and Fast boot disabled in the BIOS Settings I have USB as my first boot option I have tried both the USB 2.0 and 3.0 ports Yet, Mint is all that will boot up. Anybody have a similar issue? If it helps, the computer is a Toshiba Satellite S855D Laptop with an AMD APU quad-core processor (3 CPU, 1 GPU)

• Switching to Linux, Need backup help

  - by Stephen

  I have an existing Vista installation on my thinkpad x200 and I want to install Linux on my machine. I've done this several times already but I usually format the whole disk and dual boot on Windows and Linux. Which means I have to reinstall and reconfigure everything I had on Windows. What I want to do is backup my windows installation (into an image) and start a clean Linux installation, and run the windows image thru Vmware or Virtualbox. Whats the easiest way to do this? any free tools available? I've seen acronis but dont wanna buy it for a 1 time session only.

• connect to paltalk server using a proxy

  - by user40026

  Hi I want to use paltalk, which is a kind of chat software, but the ports that this applications uses are closed in my country. What I need to do is to use a proxy server. Unfortunately the software itself does not provide a proxy setting. I though it would be possible to run paltalk on an O.S. installed on a virtual machine (say virtualbox) and configure the network setting of virtual machine to direct all its traffic through a proxy on host Operating system, but I could not find a way to do so neither. can anyone please help me?

• How to correctly set up iWARP? Preferably on loopback

  - by ajdecon

  iWARP is a protocol for doing remote direct memory access (RDMA) on top of TCP/IP, so that it can work with Ethernet and other network types as opposed to Infiniband. It works with many of the standard IB interfaces - the IB verbs, for example - so it's all pretty transparent. I'm doing some IB-verbs programming (mostly for the sake of learning about how they work better), and it'd be wonderfully convenient for me if I could use iWARP to do RDMA over my loopback interface, so that I could test some of my code without getting on our IB-connected cluster. :-) But I cannot figure out how to get a "local development environment" set up: there are no tutorials I'm aware of for even setting up iWARP from scratch on a server or a network interface. Can anyone give me a tutorial or point me in the right direction? Environment is Fedora 16 running in VirtualBox.

• How to specify a different ip address in virtual box guest os

  - by Nrew

  I am using Windows 7 as the host. And xp as guest. I've already check out this site: http://forums.virtualbox.org/viewtopic.php?f=3&t=17232 But the info is not complete. What do I need to set here, so that the guest would have another IP Address but can still connect to the internet. Because what I'm trying to accomplish here is to be able to try Team Viewer or Cross loop. With the host os and guest os. Because I only have one computer.

• negative time for a ping echo reply

  - by Mario

  I was happily pinging in the net when suddenly: Pinging X with 32 bytes of data: Reply from .235: bytes=32 time=1444ms TTL=41 Reply from .235: bytes=32 time=1767ms TTL=41 Reply from .235: bytes=32 time=1531ms TTL=41 Reply from .235: bytes=32 time=-1198187ms TTL=41 Ping statistics for .235: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 1444ms, Maximum = -1198187ms, Average = 1073443462ms A negative time for the reply. I checked wireshark and it had the same values: Time delta from previous displayed frame: -1198.187867000 seconds Time since reference or first frame: -1179.935038000 seconds I didn't change the time of the machine while pinging. This was made in my local network at home, from a XP VM in windows 7. So I blame the VM (virtualbox). But I was wondering if this strange behaviour (to me) could have a reason, or if any of you have seen this before. Thank you bye.

• Apache does not serve non-locally

  - by yodaj007

  I have a freshly installed instance of Fedora Core 16 inside VirtualBox using bridged networking. On it, as root I typed in: yum -y install httpd service httpd start ifconfig Inside the VM, I can open a web browser to 'localhost' and I get the Apache test page. It works. But in Windows (the machine hosting the VM), I point my browser to the IP address returned by ifconfig (192.168.2.122). The connection times out. I can go to a command prompt and ping the VM. Is there a firewall or something that comes with Fedora by default? Or is there something I need to change in a config file?

• How to install GNOME desktop from DVD on CentOS 6 using the command line?

  - by alwbtc

  I have installed CentOS 6 in Virtualbox. Although I have chosen to install General Purpose GNOME Desktop, the GNOME desktop does not start. All I get is a black and white text prompt. I would like to know how I can install GNOME Desktop from the CentOS DVD. How do I mount the DVD image? How do I install GNOME desktop from command line? If I already have the GNOME Desktop installed, why doesn't it start? How can I check from command line that I have GNOME installled? This virtual machine does not have internet connection, that's why I want to install the GNOME Desktop from DVD.

• Is there anything that can be done to make X forwarding over LAN less painful?

  - by Earlz

  I have two *nix machines that I like to remotely do graphical things sometimes with. One of those machines is my Arch Linux media server, and another is my OpenBSD router/general server. My current task was installing a Windows XP over virtual box on my media server. I preferred to do the installation from my main workstation so that I could continue to watch TV from my media server on it's "actual" display. I soon noticed that X forwarding is quite painful though, even over low-latency LAN connections. Are there any settings I can tweak to make it a bit less painfully slow, jittery, and laggy? My LAN is rather small, 100Mbit, and ping times to the other box average at about 0.15ms. Also, I know Virtualbox has a VNC mode it can use instead of doing X forwarding, but this particular task was just an example

• What would happen if I did a "Boot to VHD" to a VHD that was configured to run under Hyper-V?

  - by tbone

  Microsoft has a Hyper-V based VM I'm interested in running, however, I don't have access to a Windows Server 2008 machine to try it on, only a Windows 7 Pro x64 machine (Windows 7 does not support Hyper-V). This is the VM in question: This download contains three Windows Server 2008 R2 SP1 Hyper-V Virtual Machine set for evaluating and demonstrating Office 2010, SharePoint 2010 and Project Server 2010. 2010 Information Worker Demonstration and Evaluation Virtual Machine (SP1) http://www.microsoft.com/en-us/download/details.aspx?displaylang=en&id=27417 I came across a somewhat relevant article from Scott Hanselman: Less Virtual, More Machine - Windows 7 and the magic of Boot to VHD: http://www.hanselman.com/blog/LessVirtualMoreMachineWindows7AndTheMagicOfBootToVHD.aspx I realize other options are to convert this VM to a VMWare compatible VM or some of the options to run it under VirtualBox. But instead of those routes, I'm wondering: What would happen if I tried to go the "Boot to VHD" route using this Hyper-V VHD? Is it possible that during the boot process, Windows would simply notice that hardware had changed and adjust accordingly, installing the appropriate drivers and continuing on without a hitch?

• Windows 8.1 Professional Hyper-V - can I create my own linux VM through it?

  - by KevinM1

  I have a Windows 8.1 Professional desktop, and would like to have a Linux Mint VM on it so I can do some opensource web development work. I've tried VirtualBox, but it's giving me an IO error during the Mint .iso installation. VMWare Player flat out tells me it can't install because I have Hyper-V on my machine by default. My biggest concern is nuking the desktop, which is where I do most of my non-development work/browsing/etc. The desktop seems to be listed as a VM itself in the Hyper-V Manager, and I don't want to accidentally break it. So, two questions: Can I create the Mint VM I want/need for my work? Can I do it without messing up the desktop?

• Using Windows 7 XP Mode for games

  - by Josefvz

  Hi all. I have Win 7 (x64) at home and I want to play some old games (specifically Lands of Lore 3, but also some others). This game does not work properly on Win 7, and there are no patches that I'm aware of to fix its issues. Can I use XP Mode to play this game (and other non Win 7 nice games), or is there a better way? I only have one PC and dual booting scares me... (so no to dual booting!) Another question: Will I have full hardware support (full use of my graphics card, etc) when I use DOSbox or a VM? I have decided to go with VirtualBox or vmware, I'll check which one gives the best performance, thanks for your input!

• Quick and dirty user management service for Linux VMs?

  - by quack quixote

  Background I have a home server running Debian, and a workstation that runs various VirtualBox VMs (mostly Linuxen but some Windows). At the moment, I'm creating my main user account anew for every new Linux VM. I'd like to make use of a centralized user-management scheme instead, so I can just configure the new VMs for the directory technology and let them handle user lookups automatically. The last time I worked with anything like this, NIS+ was still in fashion. I have a vague notion of what LDAP and Active Directory are, but no knowledge of how to configure them for what I want. Question What user-management/network-directory technology should I use for providing user accounts to my network? The server must run on Debian Lenny. Client configuration should be simple point-at-server-and-go. I need an example configuration for one sample user account. (nice-to-have) I may want to mount the user's home directory from the server. (nice-to-have) The same configuration works with Windows clients.

• How come Win+R prompt can open Python when it's not in my path?

  - by houbysoft

  When I use the run prompt in Windows XP Professional (Win+R), and type python.exe or python, it works and greets me with the python prompt. However, when I start a cmd window, and then type python.exe or python, it doesn't find it. This is what I expect, as the Python directory (for me, I:\Python31\) is not in my PATH. How come, then, that if I type python.exe in the Win+R prompt, it works? Edit: here is a partial output of SET, I removed most irrelevant entries, I'm not sure why is it useful, apart from the PATH variable which I already said doesn't include the Python directory. If you need a particular variable other than these, please ask. CLIENTNAME=Console CommonProgramFiles=I:\Program Files\Common Files ComSpec=I:\WINDOWS\system32\cmd.exe FP_NO_HOST_CHECK=NO OS=Windows_NT Path=I:\WINDOWS\system32;I:\WINDOWS;I:\WINDOWS\system32\WBEM;I:\WINDOWS\system32\WindowsPowerShell\v1.0;I:\Qt\2010.05\mingw\bin;I:\Program Files\CMake 2.8\bin PATHEXT=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.PSC1 ProgramFiles=I:\Program Files PROMPT=$P$G SESSIONNAME=Console SystemDrive=I: SystemRoot=I:\WINDOWS VBOX_INSTALL_PATH=I:\Program Files\Oracle\VirtualBox\ windir=I:\WINDOWS

• Recovering from bad ownership

  - by Christian Sciberras

  I was going to change the ownership of a directory to apache:apache, but I ended up running: chown -R apache:apache / Bad! Very bad! I knew what was going on when it started saying: chown: changing ownership of `/proc/2694/fd/48': Permission denied That's when I stopped everything (Ctrl+C). The current system I have is a server running virtualbox running CentOS 5. This problem happened inside the VM. Currently, everything seems to be working, but I have not restarted the system yet, and to be honest, I'm afraid that if I did something will break. I do not know chown's order, should I be concerned and assume something will break after a reboot? Is there a way to recover form this problem without having to rely on backups? I do have a daily one, but I thought there may be a simpler way out.

• Windows 7 [virtualized] resolutions in Macbook Pro Retina

  - by Trevor Sullivan

  So, I was considering picking up a Macbook Pro Retina, but then I realized that Apple forces you to scale the resolution, so you don't actually see the true benefits of the 2880x1800 display. Instead, you see upscaled, pixelated icons -- I saw this for myself in an Apple store a couple days ago. That's ok though, because the main reason I'd purchase one is to run Windows 7 on it, however I understand that the bootcamp drivers have not been updated to work with the MBP Retina. Instead, the option would be to run Windows 7 virtualized, but I haven't found any conclusive evidence to indicate whether the entire 2880x1800 resolution would act the same virtualize (VMware Fusion, VirtualBox, Parallels) as running Windows 7 natively. My question is: Does Windows 7 see the entire 2880x1800 virtualized, same as running it on bare metal (boot camp)?
