I'd like to find out why processor.sys fails, but the .1->.2 change isn't any help unfortunately. It looks like here too there are two bugs involved: one in kvm which doesn't act like processor.sys expects it, and one in processor.sys which causes it to UNLOAD_ITSELF_WITHOUT_CANCELLING_PENDING_OPERATIONS. You might try running with kvm trace enabled and look at msr and cpuid accesses just prior to the crash.

I've had a quick look at this, and I can't work out how to enable kvm trace in Kconfig. Is there any documentation on how to build with kvm trace enabled for debugging?


CONFIG_FTRACE, CONFIG_TRACEPOINTS should be sufficient, I think. 2.6.32 or later IIRC.
