[Bug 1045027] [NEW] iPXE kills kvm with KVM: entry failed, hardware error 0x80000021

[Dave Gilbert]

Public bug reported:

This is a regression - I was using iPXE last night just fine on the same
hardware (an i7-860)

I've got a guest (xml attached) with no discs that I'm trying to
netboot, but as soon as iPXE starts I see:

iPXE (PCI 00:03.0) starting execution...

and it stops - the libvirt log shows:


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.
