Description of problem:
Starting with kernel kernel-3.5.3-1.fc17.x86_64 I can't use qemu-kvm on my machines. After hang qemu-kvm process is stopped, unable to continue with booting. Reverting back to kernel 3.5.2 works for me as workaround.

Version-Release number of selected component (if applicable):

Latest working kernel:

How reproducible:

Steps to Reproduce:
1. qemu-kvm -m 1024
Actual results:
Error message in terminal:
KVM: entry failed, hardware error 0x80000021

If you're running a guest on an Intel machine without unrestricted mode
support, the failure can be most likely due to the guest entering an invalid
state for Intel VT. For example, the guest maybe running in big real mode
which is not supported on less recent Intel processors.
