Boot F17 x86_64 box with kernel-3.5.3-1 and try to iPXE network boot a new VM. The process hangs during the iPXE phase and a crash in KVM is reported in the log file.
Steps to Reproduce:
1. boot F17 x86_64 box with kernel-3.5.3-1
2. iPXE network boot a new VM
3. error: KVM: entry failed, hardware error 0x80000021

a succesful iPXE network boot
This bug has also been reported and discussed here:
The suggestion in the Ubuntu bugreport to load the kvm_intel module with emulate_invalid_guest_state=y did *not* result in a working iPXE boot when running kernel 3.5.3-1.
