* qubesos/pr/111:
vm: drop 'internal' property
qmemman: make sure to release lock
qmemman: fix meminfo parsing for python 3
devices: drop 'data' and 'frontend_domain' fields, rename 'devclass' to 'bus'
Reference objects, not their IDs - this way when object is modified, it
is visible everywhere where it is used. Main changes:
- volume.pool - Pool object
- volume.source - Volume object
Since volume have Pool object reference now, move volume related
functions into Volume class (from Pool class). This avoids horrible
`storage.get_pool(volume).something(volume)` construct.
One issue here is since volume.source reference a Volume object from a
different VM - VM's template, now VM load order is important. Since we
don't have control over it, initialize vm.storage when needed - possibly
while initializing storage of different VM. Since we don't have cycles
in AppVM-TemplateVM dependencies, it is safe.
Also, since this commit, volume.source (if defined) always points at
volume of the same name from VM's template. Using volumes with something
else as a source is no longer supported.
QubesOS/qubes-issues#2256
Use '<option name="option_name">option_value</option>' instead of
'<options option_name="option_value"/>'. It's more consistent with the
rest of qubes.xml - have one thing per element.
Also, add options deserialization test.
While at it, adjust implementation to specification: tags don't have
value, only one bit of information (present/not present).
FixesQubesOS/qubes-issues#2686
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
1. It is unclear yet whether dispvm_netvm will be implemented in core3, but
probably not.
2. Remove tests for setting memory/cpu above host resouces - rejecting
those values at property set time would break backup restore on some
machines (when migrating from bigger to smaller system).
Since qvm-prefs is now a generic tool without any property-specific
stuff, we can tests properties getters/setters in QubesVM class unit
tests.
Now most of properties are tested. Some of those tests still fails
because missing/incomplete underlying implementation.
