This series adds a qtest entry to test virtio-net failover feature.
We check following error cases:
- check missing id on device with failover_pair_id triggers an error
- check a primary device plugged on a bus that doesn't support hotplug
triggers an error
We check the status of the machine before and after hotplugging cards and
feature negotiation:
- check we don't see the primary device at boot if failover is on
- check we see the primary device at boot if failover is off
- check we don't see the primary device if failover is on
but failover_pair_id is not the one with on (I think this should be changed)
- check the primary device is plugged after the feature negotiation
- check the result if the primary device is plugged before standby device and
vice-versa
- check the if the primary device is coldplugged and the standy device
hotplugged and vice-versa
- check the migration triggers the unplug
-> this one needs to be improved as we can't actualy unplug the
card as the qtest framework doesn't allow to really do
the OS level unplug. So we receive the UNPLUG_PRIMARY
event but nothing more.
There are two preliminary patches in the series:
- PATCH 1 makes available functions that helped me to debug
the qmp command result. I think it's a good point to have them
available widely
- PATCH 2 introduces a function to enable PCI bridge.
Failover needs to be plugged on a pcie-root-port and while
the root port is not configured the cards behind it are not
available
Laurent Vivier (3):
qdict: make available dump_qobject(), dump_qdict(), dump_qlist()
qtest/libqos: add a function to initialize secondary PCI buses
tests/qtest: add some tests for virtio-net failover
