qubes: new devices API
FixesQubesOS/qubes-issues#2257
Instead of old per-VM flag 'pci_strictreset', now implement this as
per-device flag using features. To not fail on particular device
assignment set 'pci-no-strict-reset/DEVICE-BDF' to True. For
example 'pci-no-strict-reset/00:1b.0'.
QubesOS/qubes-issues#2257
Implement required event handlers according to documentation in
qubes.devices.
A modification of qubes.devices.DeviceInfo is needed to allow dynamic,
read-only properties.
QubesOS/qubes-issues#2257
Allow device plugin to list attached and available devices. Enforce
at API level every device being exposed by some domain.
This commit only changes devices API, but not update existing users
(pci) yet.
QubesOS/qubes-issues#2257
Some tests do not apply, as there is no savefile and attributes
propagation is much simpler. Dropped tests:
- test_000_firewall_propagation
- test_001_firewall_propagation
- test_000_prepare_dvm
QubesOS/qubes-issues#2253
Do not access vm.libvirt_domain after it being already removed - this
will redefine it again in libvirt, just to undefine it in a moment.
On the other hand, few lines below there is fallback libvirt cleanup, in
case of proper one not working.
Now failure to load external tests shows in which entry point the error
happened and a useful traceback. The traceback extends from the "try"
statement down to the actual error line, but it does not include the
frames above, ie. from the invocation to the load_tests routine. This is
a limitation of Python itself and usually not a problem.
