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 and the hotplug
There is one preliminary patch in the series:
- PATCH 1 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
v2:
- remove PATCH 1 that introduced a function that can be replaced by
qobject_to_json_pretty() (Markus)
- Add migration to a file and from the file to check the card is
correctly unplugged on the source, and hotplugged on the dest
- Add an ACPI call to eject the card as the kernel would do
