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
