This question has been bugging me for a while...are Windows Virtual PC or WMWare Player x64 programs? I know VirtualBox is x86.

What difference do you feel it would make? It's hard to imagine wanting to allocate more then 4 gigs of ram to a virtual machine

I believe the question was not if the virtual machines are or can be 64-bit. Instead, the question was if the virtualization applications, platforms, are x86 or x64. As such, the question is IMO valid.

If I understood the question wrong, thus giving the wrong answer earlier, let's try again: You can not run 64-bit OS's on Virtual PC, but both VMWare and VirtualBox allow it (Can I run 64-bit VM guests on a 32-bit host? - Server Fault and Creating New VM, CPU not 64 bit error).

I can think of several reasonable scenarios to run a 64-bit guest, which has been allocated 4GB+ RAM.

Just as an observation; Virtual Box has had a few problems with 64bit OSs at the moment, mostly due to installation issues and virtual processor architecture, so it's worth checking to see if the bugs have been zapped yet.

I didn't mean to imply that the OP's question was invalid. I would be interested to hear about the scenarios where it would be desirable to run a 64bit guest VM with 4+ gigs of ram. And thanks for the link which talks about running a 64bit guest VM on a 32bit Host. I would not have thought it possible.
