Description Patrick 2012-09-10 04:10:25 UTC 
Description of problem:
With kernel 3.5.3-1 doing an iPXE network boot results in a KVM crash. Kernel 3.5.2 works

Version-Release number of selected component (if applicable):
Kernel 3.5.3-1.fc17.x86_64

How reproducible:
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
  
Actual results:
error: KVM: entry failed, hardware error 0x80000021

Expected results:
a succesful iPXE network boot

Comment 1 Patrick 2012-09-10 04:12:54 UTC 
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.
