If event_inj is valid on a #vmexit the host CPU would write
the contents to exit_int_info, so the hypervisor knows that
the event wasn't injected.
We don't do this in nested SVM by now which is a bug and
fixed by this patch.
We need to start thinking about regression tests for these bugs. It
would be relatively easy to set up something with save->cr3 == cr3
(i.e. no isolation, mmu virtualization, etc.).
Should be doable with a in-kernel regression test-suite module, I think.
Triggering such (race-condition like) test cases from userspace is
somewhat hard.
Isn't it sufficient, for this case, to inject a nested interrupt when
the nested idt is not mapped?
