[kvm-unit-tests,v1,0/3] Add panic test support

Message

QEMU suports a guest state "guest-panicked" which indicates something in
the guest went wrong, for example on s390x, when an external interrupt
loop was triggered.

Since the guest does not continue to run when it is in the
guest-panicked state, it is currently impossible to write panicking
tests in kvm-unit-tests. Support from the runtime is needed to check
that the guest enters the guest-panicked state.

This series adds the required support to the runtime together with two
tests for s390x which cause guest panics.

Nico Boehr (3):
  runtime: add support for panic tests
  s390x: add extint loop test
  s390x: add pgm spec interrupt loop test
