Greetings & Thanks,

*Can several Virtual Machines exist under Windows 7? Say, Virtual Box and Windows Virtual PC.
*If they can exist, can they run at the same time?

I ask because I need to run Windows XP Mode under Win 7, and I use Virtual Box to run Ubuntu.

Can Windows XP Mode run under Virtual Box? That would solve my problem.

Thanks,
Anraoi

Short answer is not they cannot.
Running another virtualizer inside of VirtualBox is not supported. Plus they will not work in parallel either You can not run 2 hardware-v hyper-v appliances together. It would probably kill the OS if you did got it to work.

No, you probably can't run XP Mode under Virtualbox. You can probably get it to install (if you know what you are doing and realize that the XP Mode vhd is a base vhd for a differencing disk) but not activate.

You can't install VPC 2007 while WVPC (the Windows 7 version) is installed (it is blocked by Microsoft) but you can install WVPC (or VPC 2007) side by side with VirtualBox. You can install both but you cannot run them simultaneously if you use Hardware virtualization. The one you start first will lock on to hardware virtualization and prevent the other from starting. As Perry pointed out, you can't run VPC or VBox in a virtual machine.

I have a Win 7 X64 Pro with hardwarwe virtualization running XP Mode under WVPC and I have VirtualBox 3.1.2 installed on the same system. It work fine as long as I don't try to run both at once. They both use bridged networking and Windows happily installs both filter drivers, VPC and VBox.

I also have another Win 7 Pro machine which does not support hardware virtualization. It has both VirtualBox and VPC 2007 installed (no XP Mode). Ubuntu runs fine under VirtualBox on this machine. I have never tried to run both VPC and VBox at the same time.

Try the VMLite XP Mode Plugin for Sun VirtualBox v3.1.2.
At 57MB, that is not really a plugin, I suspect it entirely replaces VirtualBox 3.1.2 with a different version, which I'm not even sure is entirely the same as VirtualBox in other areas, but allegedly allows Windows XP Mode.

Thanks to all.
