I am about to buy a quad core system and wonder how many cores a Windows XP system running under Linux (kernel 2.6) can effectively use. If I run video encoding under the virtual XP, how many cores will be utilised (assuming the host system is mostly idle)? If quad core isn't used, will the system at least make use of two cores? Has Innotek run any benchmarks on this?
Really appreciate your answer as that's a really important issue for me. Thanks!

It seems that the point of all this is that it doesn't. I've been trying to find out if anyone is going to enable such, but at this time it looks like there's no way to get VCPUs running on a guest OS.
My host is Fedora 7, and while I've had great luck with VirtualBox running Vista and Win2003 guests, it's for single-CPU only. For multiple CPUs, I have QEMU running other Linux guests on a F7 host, but have not successfully gotten a Windows guest to run. But in Qemu you can just select how many VCPU's you want to allocate to a guest, and if you have them available, you can use them.
