Now that my Dell Machine has a lot of RAM (8 GB) and hard disk space, it is quite easy to run 4 virtual machines at the same time, each one utilizing 1 GB of RAM, 2 cores and/or threads, 3D acceleration with 128 MB of video RAM. Windows XP also has 2D acceleration on. Arch Linux also has guest additions installed with GNOME 3 performing almost perfectly. By saying almost, I mean, it has awkward full screen behaviour. It might be a bug in GNOME’s virtual box support.
All of these and still having almost 2 GB free. And not only that, I am also running Vuze torrent client (a.k.a. Azureus), Skype, Opera, Clementine and various backround programs.
In the screenshot you can see four VirtualBox machines, Arch Linux, Backtrack 5 R1, Backbox 2.01, Windows XP Performance Edition
Look at the top of my current desktop, the Core Temp gadget:
Bellow a screenshot of the Windows Task Manager, Processes tab:
What is your success with VirtualBox, or VMware?
I like VirtualBox more than any other virtualization software out there. In its later versions it provides compatibility with VMware disk images and has many new features.
And yes… you can access your physical disks and/or other physical media like usb sticks!
a. From Linux:
In a terminal window type the following (as user, you dont need to be root):
VBoxManage internalcommands createrawvmdk -filename ~/.VirtualBox/Harddisks/myphysicaldisk.vmdk -rawdisk /dev/sdX
where /dev/sdX is the physical disk you like to access. If you dont know what device node your disk has, type the following command:
Note: To use all the features as user flawlessly, dont forget to add your user to the vboxusers group.
b. From Windows:
Note: Command Line cmd.exe and VirtualBox GUI have to be run as administrator in order to successfully create and use the newly created virtual-to-physical disk!
cd C:\Program Files\Oracle\VirtualBox\
VBoxManage.exe internalcommands createrawvmdk -filename c: \Users\yourusername\.Virtualbox\VDI\mydrive.vmdk -rawdisk \\.\PhysicalDriveX
Where X is a number. 0 (zero) for the first hard disk, 1 is the second one mounted and so on.
Now all that’s left is to add the vmdk virtual image file to your virtual machine via the VirtualBox GUI.
Warning!: Do not attempt to boot your existing OS installed in the physical media through a virtual machine, as it may lead to data corruption and/or file loss! Try it only of you want to experiment, however be prepared for data loss. You have been warned!
