Threis no more ntpd service used - new approach do not conflict with
ntpd. Because of this, new feature is named 'service.clocksync', and
should be _enabled_ in ClockVM ('ntpd' was disabled there).
QubesOS/qubes-issues#1230
When an API call is interrupted, the relevant coroutine is cancelled -
which means it may throw CancelledError. At the same time, cancelled
call have related socket already closed (and transport set to None). But
QubesDaemonProtocol.respond try to close the transport again, which
fails. Fix handling this case.
Get a VM statistics once. If previous measurements are provided,
calculate difference too. This is backend part of upcoming
admin.vm.Stats service.
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.
Only qubesd should load qubes.xml directly. Put a TODO comments for now
in place of slow VM reporting, invent some better mechanism later.
This loading of qubes.xml caused deadlocks, because qmemnan kept open
file descriptor (in locked state).
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.

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

Some events are internal for a sole purpose of getting some data from
extension. Since listeners of admin.Events cannot return anything, there
is no sense in sending those events there.
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.
Since we have LVM by default, it is possible to backup VMs while they
are running. For now it will include its state from before startup, but
later we may implement some other logic (a snapshot of running VM).
