Berrangé, Juan Quintela, Michael Roth, Michael S. Tsirkin, Gerd Hoffmann, Igor Mammedov, Ani Sinha, Paolo Bonzini, Jens Freimann 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 ^ permalink raw reply [flat|nested] 10+ messages in thread

Berrangé, Juan Quintela, Michael Roth, Michael S. Tsirkin, Gerd Hoffmann, Igor Mammedov, Ani Sinha, Paolo Bonzini, Jens Freimann Failover needs to detect the end of the PCI unplug to start migration after the VFIO card has been unplugged. To do that, a flag is set in pcie_cap_slot_unplug_request_cb() and reset in pcie_unplug_device(). But since 17858a169508 ("hw/acpi/ich9: Set ACPI PCI hot-plug as default on Q35") we have switched to ACPI unplug and these functions are not called anymore and the flag not set. So failover migration is not able to detect if card is really unplugged and acts as it's done as soon as it's started. So it doesn't wait the end of the unplug to start the migration. We don't see any problem when we test that because ACPI unplug is faster than PCIe native hotplug and when the migration really starts the unplug operation is already done.
