- Prefer instance attributes over local variables - the former ones do
not leak into traceback object and are cleaned up by tests framework.
- Use 'with' syntax for handling files.
- Use subprocess.DEVNULL instead of open('/dev/null') where applicable
- Delete local variables when not needed anymore.
- Fix str/bytes
- Call skipTest as early as possible - before doing any setup
- Fix networking tests - configuration commands needs to be called as
root (missing user= argument).
- Fix setting firewall - policy is no longer changeable
- Add missing loop.run_until_complete() calls.
- Convert subprocess.Popen to asyncio.create_subprocess_exec where
needed (when called process needs to communicate with qubesd).
- Cleanup processes (call .wait()).
There is no more significant difference between PV and HVM. VMs are HVM
by default anyway. More important for this test is difference between
Linux (with Qubes packages installed) and other OS-es. Rename tests
accordingly. The later one is still incomplete.
The most important change is doing vm.close() when removing domain -
this means it wouldn't be cleaned later by iterating over app.domains.
Other changes include removing VMs in the right order, regarding netvm
dependency (otherwise killing or removing may fail). And one more
missing coroutine handling (in shutdown_and_wait).
Catch exception there and log it. Otherwise asyncio complains about not
retrieved exception. There is no one else to handle this exception,
because shutdown event is triggered from libvirt, not any Admin API.
Allow to get domain class as a property, not using admin.vm.List call.
This makes it unnecessary to call admin.vm.List on the client side to
construct wrapper object.
There is intentionally no default template in terms of qubes.property
definition, to not cause problems when switching global default_template
property - like breaking some VMs, or forcing the user to shutdown all
of them for this. But this also means it shouldn't be allowed to reset
template to "default" value, because it will result in a VM without
template at all.

If VM startup failed before starting anything (even in paused state),
there will be no further event, not even domain-shutdown. This makes it
hard for event-listening applications (like domains tray) to account
domain state. Fix this by emiting domain-start-failed event in every
case of failed startup after emiting domain-pre-start.

Recently libvirt removed support for changing event implementation.
Therefore we have to use a single, global one and we check if it is
empty between tests.
In contrast to the cirrus card emulation the vga card supports more
video modes. Since the qemu gui-agent bug [1] is now fixed we can switch
back to use it.

On certain locales (e.g. danish) `usage_percent` will output a comma-separated number, which will make `attr` point the last two decimal points, s.t. `return vol_info['attr'][4] == 'a'` (in the `verify` func) will fail and `qubesd` wont run.
This will make analyzing the policy code slightly easier. While it makes
verify_special_value function more complex, other places are much
simpler now.

'dispvm_allowed' name was confusing, because it suggested being able to
spawn new DispVMs, not being a template for DispVM.
FixesQubesOS/qubes-issues#3047
Clone properties from DispVM template after setting base properties
(qid, name, uuid). This means we can use standard clone_properties()
function. Otherwise various setters may fail - for example
netvm setter require uuid property initialized (for VM lookup in VM
collection).
Also, make dispvm_allowed check more robust - include direct creation of
DispVM, and also check just before VM startup (if property was changed
in the meantime).
FixesQubesOS/qubes-issues#3057
qvm-sync-clock in dom0 now synchronize only dom0 time. For VM time,
qvm-sync-clock needs to be called in VM. Also, both will communicate
with qubesd, so must be called asynchronously from tests.
