Here are tips for Virtual Machines (VirtualBox, VMware Workstation, Virtual PC under Windows 7 and Hyper-V under Server 2008 R2). Â
If you want to run Linux virtual machine under Windows, it is better to use VirtualBox or VMware (Virtual PC is so awkward for Linux).
How can I install Hyper-V ?For consumer OS like Windows 7 or 8, Hyper-V is installed from "Add Windows Feature". It turned out that Server 2008 uses Server Manager "Add Roles". How can I have the VirtualBox shared directory permission?When you create a virtual box Ubuntu, the shared directory is mounted in /media/sf_(NameOfSharedDir), i.e. /media/sf_Videos when I named the shared directory as "Videos".Unfortunately, when I tried to cd to /media/sf_Videos, I get permission denied.The solution was found here http://unix.stackexchange.com/questions/52667/file-permission-issues-with-shared-folders-under-virtual-box-ubuntu-guest-wind. sudo usermod -aG vboxsf ytosa logout and login again (to make softlink visible) ln -s /media/sf_Videos /home/ytosa/sharedwhere ytosa is my username on Ubuntu. Now my home directory has shared directory by soft link. How can I test VT-X working?In order for virtual machine to use more than 1 cpu, VT-X must be available. It must be setin BIOS. This feature is available under recent CPUs. In my case Oracle Virtual Box setting showed CPU greyed out for a virtual machine. Its log revealed that 00:00:01.399 HWACCM: No VT-x or AMD-V CPU extension found. Reason VERR_VMX_NO_VMX. I needed the confirmation. Microsoft has the software to check http://www.microsoft.com/download/en/details.aspx?id=592 but it won't run on Windows Server 2008 R2. It turned out that SecurAble.exe which is available at http://www.grc.com/securable.htm can run under Windows Server 2008 R2. I found another tool provided by VMWare which also gives more detailed information. The software, vt.iso, is obtained from http://communities.vmware.com/docs/DOC-8978/version/19 which you must burn a CD and boot from it. Both of these confirmed that VT-X is not availab.e I coould not find the cause and I ended up reinstalling Windows Server 2008 R2 all over gain. After that, VT-X is available and was able to install Windows 8 Beta. How can I convert VirtualPC .vhd to VirtualBox .vdi?Windows 7 Professional owner is allowed to download Windows XP SP3 .vhd to their PC.Since Virtual PC is so lame, I wanted to use it under Virtual Box. The method described below did not work for me after spending 3 hours. Too bad. (Someone did figure outhow to do in http://www.qc4blog.com/?p=721.It is best to use "Ubuntu" Linux so that the downloading of qemu can be done easily by apt-get install qemu. Note that when you do "qemu-img convert -O raw myfile.vhd myfile.bin", it will create the maximum disk size file it was configured to. In my case the original file was only 9 Gbyte but it created a 127 Gbyte raw file (which is the maximum size under Virtual PC). Thus you have to make sure that you have enough disk space. The conversionfrom raw to .vdi is done by VirtualBox command called VBoxManage which exists inProgram Files\Oracle\VirtualBox directory. ) How can I share Windows directory under VirtualBox?OBSOLETED: VirtualBox mount Shared Directory as /media/sf_(SharedDirectoryName). For permission issue, look at the top item. VirtualBox sharing is not automatic like VMware, even though you specify the sharing under Virtual Machine setting. You have to mount the shared folder by hand. mount -t vboxsf (sharedName) /mnt/sharewhere (sharedName) is the one you specified as the Folder name. Note that I mount it at /mnt/share directory. How can I make the virtual harddisk size bigger?In both VirtualBox and VMware, you specify the virtual disk size when you createa virtual machine. The question is how to make it bigger after you created a virtual machine.It turned out that VMware workstation supplies the tool at Virtual Machine Settings → Hard Disk → Utitilities → Expand .... In VirtualBox, it is more painful.see http://forums.virtualbox.org/viewtopic.php?t=585. How can I get higher resolutions in VM?I initially got only 800x600 under Ubuntu 10.04 and CentOS 5.5 installation underVirtualBox. VMware Workstation was able to get higher resolution under Ubuntu 10.04 and CentOS. If you use the custom instal, then I only get 800x600 resolution. It turned out that the default Linux install does not recognize the virtual video card in both VirtualBox and VMware and thus assigns VESA as the video card. That is why 800x600 is the maximum resolution. Here is the step:
VortualBox
CentOS 5.5 case: (after the standard iso install)
1. Make sure that you install updates and then add Developer Tools.
2. Run Install Guest Additions from the VirtualBox window menu.
3. CentOS will mount VBOXADDITIONS_3.2.6_6312 into /media/
4. When you run, autorun.sh will produce "bin/sh: bad interpreter: Permission denied"
This error is due to autorun.sh referring to "gksu" at line 44.
Quick fix is to copy CD to your local directory and edit autorun.sh to remove gksu.
5. You become "su".
6. sh ./autorun.sh
Ubuntu 10.04 case:
1. Run "Install Guest Additions" from the VirtualBox window menu.
2. You have to mount the virtual CD.
3. sh ./autorun.sh
will cause the messagebox asking su (gksu exists on Ubuntu 10.04).
VMware Workstation
1. This process is required only when you pick custom install. CentOS 5.5 is required to
to do custom install, since the automatic install creates the root partition size
of only 3 Gbytes and thus you cannot install developer tools.
2. Run VM->VMware Tools
Compare Virtual Machines available at this timeCurrently there are four Virtual Machines available. VMware, VirtualBox, Virtual PC and Hyper-V.I could not find information on the emulated hardware for each machine and thus I tried them all by installing Ubuntu 10.4 release and running lspci.
HyperV does not support sound emulation. The only way to get the sound is to use Remote Desktop (RDP).Here is the description on how to ( http://www.sudonym.com/61/full-sound-through-rdp-from-a-hyper-v-windows-7-vm). Home |
