Karli, Thanks for the report, there should be a resolution soon. Karli, Can you load the kvm-intel.ko module with emulate_invalid_guest_state parameter set as 0, ie: arch/x86/kvm/kvm-intel.ko emulate_invalid_guest_state=0 Its very likely the cause for this are instruction emulation upstream (emulation of invalid guest state by default). These are being fixed upstream. Once that is completed, it will be necessary to backport to FC17. In the meantime, loading kvm-intel.ko with emulate_invalid_guest_state=0 should work around the problem (tested locally on kvm.git as of dec/2012). (In reply to comment #3) > Its very likely the cause for this are instruction emulation upstream > (emulation of invalid guest state by default). "instruction emulation changes upstream". This bug is being closed with INSUFFICIENT_DATA as there has not been a response in 2 weeks. If you are still experiencing this issue, please reopen and attach the relevant data from the latest kernel you are running and any data that might have been requested previously. |
