Guest is Fedora 12 x86-64 (2.6.32.9-70.fc12). Hi, as you can see, I posted a new set of patches, which apply to the current trunk. Can you please give it another try? Thanks!

What are the problems with smp?
give the "-cpu host" option to qemu,
Why is this needed?
and the "nested=1 ept=0 vpid=0" options to the kvm-intel module in L0.
Why are those needed? Seems trivial to support a nonept guest on an ept host - all you do is switch cr3 during vmentry and vmexit.
