Hi!
The guest starts up showing the Bochs BIOS POST and stucks giving thousands of lines :

What was the value of exit_reason?
kernel/x86/vmx.c:

That's an exception or nmi. Next step is to instrument
handle_exception() and see what happens there. Please print out
vect_info, intr_info, and kvm_rip_read(vcpu) (all as hex).
The more you instrument, of course, the better.
