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 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 Laurent Vivier (4): qtest/libqos: add a function to initialize secondary PCI buses tests/qtest: add some tests for virtio-net failover failover: fix unplug pending detection tests/libqtest: update virtio-net failover test hw/acpi/pcihp.c | 30 +- include/hw/pci/pci_bridge.h | 8 + tests/qtest/libqos/pci.c | 118 ++++++ tests/qtest/libqos/pci.h | 1 + tests/qtest/meson.build | 3 + tests/qtest/virtio-net-failover.c | 681 ++++++++++++++++++++++++++++++ 6 files changed, 838 insertions(+), 3 deletions(-) create mode 100644 tests/qtest/virtio-net-failover.c -- 2.33.1
