Tests that build vrtManager objects and touch no view, form or model of
an app lived in that app; vrtManager/tests already holds such tests, so
the convention was split. They move to vrtManager/tests: the firmware,
CPU mode and PCIe port definitions of a new VM (test_create), USB and PCI
host devices, the console listener, host CPU reads, interface reads,
deletes and XML, network filters, PCI passthrough rules, node devices,
network changes, addresses and leases, pool XML, secrets, and the live
tests that use vrtManager only (disk resize, ISO, snapshots, XML, live
clone). livetest.py, the live-test helper six apps import, and the
network test driver move with them.
Others go to their app: the quota with a host down to instances, the
401/403 Logs rows (webvirtcloud's middleware) to webvirtcloud, the VM
page's tab script test to instances, novncd's own tests out of the
console views tests, the compute lock and input validation tests out of
the computes views tests, the interface views out of the forms tests.
instances/tests/test_views.py, entirely live, is test_live_views.py.
Test modules imported fixtures from each other; shared ones are now in
vrtManager/tests/fakes.py (migration fakes, node devices, IOMMU groups,
leases, a NAT network, a Ceph secret), interfaces/tests/fakes.py,
console/tests/daemons.py (novncd loaded once), livetest.wait_for and
instances/tests/create_page.BODY. Every live test checks
livetest.enabled(). The suite runs the same 2097 tests.
vrtManager's errors (some 140: a disk that does not move, a network
address outside its subnet, a host device given to another VM, the
disks a migration cannot copy) were English f-strings, so no catalog
could translate them, on pages or in jobs.
They are marked texts with their values now; a variant that differs by
a word (internal or external, running or persistent, with a subnet or
without) is a whole message of its own, and a list of problems is a
list of messages. OperationError reads in the active language, so the
pages that show one translate it as they are; its args stay English, and
so do the logs and the audit log. Host device problems and the Migrate
tab's reasons a disk is not copied are messages too.
- The Host devices tab gives a shut-off VM a PCI device of its host and
takes it back; libvirt binds the device to vfio-pci when the VM starts
and gives it back when it stops (managed). The VM's PCI devices are
listed with whether the running VM and its next start have them.
- A device is offered, and accepted on the server under the compute's
claim, only when it is no bridge of any kind (bridge header, PCIe port,
or of the bridge class: host bridge, LPC), the host has none of its own
network interfaces, disks or graphics card on it (else: bind it to
vfio-pci on the host first), no other VM names it, and every other
endpoint of its IOMMU group is the VM's too or has no driver or
vfio-pci and no other VM; bridges in the group stay with pcieport, and
a member that cannot be read keeps the group. Nothing in the group is
taken implicitly.
- A snapshot revert checks the PCI devices of the snapshot with the same
rules; migration and clones already leave host devices out.
- The add forms of the tab load together, when the tab opens.
