QubesVM.run_for_stdio() by default captures stderr. In case of call fail
(non-zero return code), captured stderr is included in the exception
object, but isn't printed by default CalledProcessError message.
Make it visible by:
- handling CalledProcessError and including in the test failure message
(when exception is captured already)
- not capturing stderr (if no exception handling is present in the
test)
The main use case for this function is to create qrexec services in VMs.
Since qrexec now require service scripts to be executable, make
create_remote_file() adjust permissions.
If any test-* VMs remains from previous test run, there are removed
before test. self.app doesn't exist at this point, so don't require it
in self.remove_vms().
This commit adds a test case for the QubesVM class's is_fully_usable
method. The verified scenarios are as follows:
* The VM has qrexec enabled, and the qrexec service has been
successfully started.
(The VM becomes "fully usable" in this case.)
* The VM has qrexec enabled, and the qrexec service has failed to start
(Error handling case; the VM is *not* fully usable.)
* The VM does *not* have qrexec enabled.
(The VM becomes "fully usable" in this case.)
Prior to this commit, a properly configured Linux HVM would not
transition from the 'Transient' state to the 'Running' state according
to qvm-ls output, even if the HVM in question had the 'qrexec' feature
disabled.
This issue is caused by an unconditional qrexec check in the
'on_domain_is_fully_usable' method, and is resolved by adding
a check that short-circuits the qrexec check if the aforementioned
feature is not enabled for the VM in question.
* origin/pr/295:
tests: fix tag name in audiovm test
tests: ensure notin while setting Audio/Gui VM
gui: add checks for changing/removing guivm
audio: add checks for changing/removing audiovm
audio/gui: use simply vm.tags instead of list()
tests: fix tests for gui/audio vm
Make pylint happy
gui/audio: fixes from Marek's comments
Allow AudioVM to be ran after any attached qubes
Allow GuiVM to be ran after any attached qubes
xid: ensure vm is not running
tests: fix missing default audiovm and guivm tags
gui, audio: better handling of start/stop guivm/audiovm
gui, audio: ensure guivm and audiovm tag are set
Support for AudioVM
Wait specifically for pulseaudio to start in the VM, instead of just
waiting few seconds.
Also, improve failure message to distinguish total lack of audio from
just missing few samples.
