This is because .tearDown() is not executed if the exception occurs in
setUp() [for example self.skipTest() raises an exception]. The lower
levels of .tearDown() being executed are critical to not leaking file
descriptors.
Add public Admin API call to create Disposable VM that would be
automatically destroyed after shutdown. Do not keep this functionality
for qrexec-policy tool only.
Also, use admin.vm.Start there, instead of internal.vm.Start and
admin.vm.Kill instead of internal.vm.CleanupDispVM (this is enough,
because DispVM now have auto_cleanup property).
QubesOS/qubes-issues#2974
Add auto_cleanup property, which remove DispVM after its shutdown
- this is to unify DispVM handling - less places needing special
handling after DispVM shutdown.
New DispVM inherit all settings from respective AppVM. Move this from
classmethod `DispVM.from_appvm()`, to DispVM constructor. This unify
creating new DispVM with any other VM class.
Notable exception are attached devices - because only one running VM can
have a device attached, this would prevent second DispVM started from
the same AppVM. If one need DispVM with some device attached, one can
create DispVM with auto_cleanup=False. Such DispVM will still not have
persistent storage (as any other DispVM).
Tests included.

QubesOS/qubes-issues#853
Remove some more references to objects holding (possibly indirectly)
reference to libvirt connection:
- local variables in tearDown function
- running Admin API calls (especially admin.Events)
- vmm._libvirt_conn directly, in case some reference to Qubes()
is still there
- any instance attribute that is an object from 'qubes' python package
(instead of just those descending from BaseVM)
- do not create new Qubes() instance for removing VMs - if we already
have one in self.app
Then trigger garbage collector to really cleanup those objects (and
close relevant file descriptors). It's important do do this before
closing event loop, because some of descructors may try to use it (for
example remove registered handlers).
When tearDownClass is executed, event loop is already closed. Since no
test really need it right now, drop support for test class-wide VMs and
convert those methods back to instance methods.
Also put coroutines (vm.remove_from_disk, vm.kill) onto event loop.
Since it is no longer child of QubesVM, constructor do not take 'qid'
and 'name' arguments.
Also:
- remove other dropped properties tests (netvm, storage related)
- make the test working in non-dom0
- improve TestPool mock - init_volume now return appropriate mock type,
instead of TestPool
- improve patching base directory (/var/lib/qubes) - it is stored in
more than one place...
- fix inheritance in TC_01_ThinPool class
- fix expected LVM volume names ('vm-' prefix)
- fix cleanup after FilePool tests - remove temporary qubes.xml
- asyncio usage
- better reporting in integ.storage - include error message in the
report, not only as a comment in code
Don't set 'source' volume in various places (each VM class constructor
etc), do it as part of volume initialization. And when it needs to be
re-calculated, call storage.init_volume again.
This code was duplicated, and as usual in such a case, those copies
were different - one have set 'size', the other one not.
QubesOS/qubes-issues#2256
Since we have app.default_pool* properties, create appropriately named
pool and let those properties choose the right pool. This also means we
don't need to specify pool name in default volume config anymore
QubesOS/qubes-issues#2256
The old format have many issues and is discouraged by tar developers. In
this case the most important one is header with possible non-ASCII
characters, which will result in UnicodeDecodeError (tarfile module
require header parts in utf-8).
PAX format is much cleaner, as it use standard mechanism for extended
headers.
Changed the inheritance hierarchy:
1. Renamed `SystemTestsMixin` to `SystemTestCase`
2. `SystemTestCase` is a child of `QubesTestCase`
3. All classes extending the prior `SystemTestsMixin` now just extend `object`
* tests-fixes-1:
api: extract function to make pylint happy
tests/vm: simplify AppVM storage test
storage: do not use deepcopy on volume configs
api: cleanup already started servers when some later failed
tests: fix block devices tests when running on real system
tests: fix some FD leaks
Use minimal TestPool(), instead of Mock().
This allow effectively compare Volume instances (init_volume with the
same parameters return equal Volume instance).
