Running the kvm-unit-tests ITS set:

   env QEMU=$HOME/lsrc/qemu.git/builds/arm.all/qemu-system-aarch64 
./run_tests.sh -g its

with a patched unitests.cfg to remove the KVM requirement I get:

  PASS its-introspection (5 tests)
  FAIL its-trigger (6 tests, 1 unexpected failures)
  FAIL its-migration
  FAIL its-pending-migration (1 tests, 1 unexpected failures)
  SKIP its-migrate-unmapped-collection (1 tests, 1 skipped)

The its-migration asserts:

  Now migrate the VM, then press a key to continue...
  INFO: gicv3: its-migration: Migration complete
  INT dev_id=2 event_id=20
  /home/alex/lsrc/tests/kvm-unit-tests.git/lib/arm64/gic-v3-its-cmd.c:192:
