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
v8:
- fix checkpatch.pl error (space after "(")
- fix sanitizer errors:
* migrate_status() qobject_unref() cleanup
* release QVirtioPCIDevice with qos_object_destroy()
* add a missing g_free() in qpci_secondary_buses_rec()
* add qobject_unref() in get_bus() and find_device()
when an object is popped from a list.
v7:
- merge patch 3 and 4 as the fix for ACPI unplug has been merged
- address Thomas' comments
- add a dependency on slirp in meson.build
- check FAILOVER_NEGOCIATED device-id and MIGRATION status
on destination, update UNPLUG_PRIMARY event checking
- fix an object_unref() in test_migrate_abort_active()
- fix typo s/whan/when/
v6:
- manage more than 2 root ports
- add a function to check if a card is available or not
- check migration state
- add cancelled migration test cases
- rename tests
v5:
- re-add the wait-unplug test that has been removed from v4 by mistake.
v4:
- rely on query-migrate status to know the migration state rather than
to wait the STOP event.
- remove the patch to add time out to qtest_qmp_eventwait()
v3:
- fix a bug with ACPI unplug and add the related test
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
