We too, and that's the only conclusion we could reach.  And the other
one that I can remember was KVM_INTERNAL_ERROR_DELIVERY_EV with
EPT_VIOLATION exits, so I would add it to all KVM_EXIT_INTERNAL_ERROR.

Nowadays KVM_EXIT_FAIL_ENTRY would probably also be an internal error,
however it was somewhat more frequent back before Intel CPUs had
unrestricted guest support.
