[Qemu-devel] [PULL 5/7] tests.acceptance: adds simple migration test
Posted by Cleber Rosa 6 years, 8 months ago 
From: Caio Carrara <ccarrara@redhat.com>

This change adds the simplest possible migration test. Beyond the test
purpose itself it's also useful to exercise the multi virtual machines
capabilities from base avocado qemu test class.

This method doesn't seem to work when running with -j2: 2 tests started
with different arch configurations get the same port... Is this a known issue?

It's not bullet proof, but it seems to be quite safe... This is what I've tried:

If this is about the issue you posted on IRC, it's about s390x and migration instead:

2020-11-03 10:06:33,124 qmp              L0255 DEBUG| >>> {'execute': 'query-migrate'}
2020-11-03 10:06:33,124 qmp              L0148 DEBUG| <<< {'timestamp': {'seconds': 1604415993, 'microseconds': 124382}, 'event': 'GUEST_PANICKED', 'data': {'action': 'pause', 'info': {'core': 0, 'psw-addr': 0, 'reason': 'disabled-wait', 'psw-mask':

I ran across this on Friday, and will properly report it.

Let me know if that helps,
