I've been trying to get WinPE to boot correctly as a KVM guest. I've
found that WinPE > 4.0 (aka server 2012) will boot fine in KVM, but
older versions will not. I only see this issue if the HyperV
enlightenments are enabled.
A screenshot of the crash can be found at:

If I change '-cpu host,hv_relaxed,hv_vapic,hv_spinlocks=0x1000' to '-cpu
host', WinPE boots up fine.
Is this a bug in KVM? I'm not really sure what other information would
be helpful here.
