It's been probably about 8 years or so since I touched QEMU, but at the time the performance was unusable (on a modest system) compared to a very usable virtualbox or vmware. IIRC, I was just trying to run win XP on Windows 7.
How do things stand these days?
Also, given that QEMU is somewhat platform independent, how well does it run an x86 OS on top of an ARM chip?

Oh yeah so for performance you would want to look into kvm which is used by QEMU.

KVM is a Linux kernel module. ineedasername says they were using QEMU on Windows 7.

Windows has a very similar hypervisor accelerator that QEMU supports called whp.
