Anything from netconsole? Kernel logs would help a lot.

Please bisect and let us know what broke this.

I have bisected that, and it turned out, that this guest has the same problem as SUSE Linux 9.1.

Which commit did git bisect point to as the one bringing in the regression?

Fixed for kvm-54:

commit 316bd49570ab7b1812bdd954ccd59ad8bc9e9ddc

KVM: Fix faults during injection of real-mode interrupts

If vmx fails to inject a real-mode interrupt while fetching the interrupt
redirection table, it fails to record this in the vectoring information
field.  So we detect this condition and do it ourselves.
