KVM: Fetch guest cr3 from hardware on demand
Instead of syncing the guest cr3 every exit, which is expensince on

Does your machine have ept?
(cat /sys/module/kvm_intel/parameters/ept)
Sure. (Assuming that the Y means yes). I am no C developer, but I was
wondering, if the issue is related to the difference in
ept_update_paging_mode_cr0 between original patch in the kvm git and the
linux-2.6. git tree.
Best regards,
Markus
