* devel-6:
qvm-ls: fix total VM size reporting
doc: update manpage of qvm-service
tools: qvm-service tool
tests: too much copy&paste
features: serialize True as '1'
tools/qvm-start-gui: add --force-stubdomain options
tools/qvm-shutdown: fix help message
tools/qvm-shutdown: drop --force option, it isn't supported anymore
New qvm-backup tool can either use pre-existing backup profile
(--profile), or - when running in dom0 - can create new one based on
used options (--save-profile).
This commit add a tool itself, update its man page, and add tests for
it.
FixesQubesOS/qubes-issues#2931
* devel-2-qvm-run-1:
Make pylint happy
tools/qvm-run: fix handling EOF
tests: mark qvm-run tests with "expected failure"
tools/qvm-run: fix handling copying stdin to the process
Launch stdin copy loop in a separate process (multiprocessing.Process)
and terminate it when target process is terminated.
Another idea here was threads, but there is no API to kill a thread
waiting on read().
VMs can have runtime dependencies - for example it isn't possible to
shutdown netvm used by some other running VM(s). Since client-side tools
may not have full knowledge about rules enforcing those dependencies
(for example may not have access to 'netvm' property), implement
best-effort approach:
1. Try to shutdown all requested VMs
2. For those where shutdown request succeed, wait for actual shutdown
3. For others - go back to step 1
And loop until all VMs are shutdown, or all shutdown requests fails.
Do not close event loop in utility function - handle it only in main().
For this reason, change appropriate functions to coroutines.

Don't fail the whole process when "just" appmenus import fails.
But if data import fails, remove the VM
Also update for vm.run_service_for_stdio raising CalledProcessError.
Don't start GUI daemon for given VM twice when qvm-start-gui was started
during VM startup (while waiting for qrexec startup). This is especially
common while running tests.
Report failed qubes.SetMonitorLayout as warning (instead of unhandled
exception).
Clear VM cache on qubesd reconnect.
Fix logging.
This way we don't need separate admin.vm.Clone call, which is tricky to
handler properly with policy.
A VM may not have access to all the properties and other metadata, so
add ignore_errors argument, for best-effort approach (copy what is
possible). In any case, failure of cloning VM data fails the whole
operation.
When operation fails, VM is removed.
While at it, allow to specify alternative VM class - this allows
morphing one VM into another (for example AppVM -> StandaloneVM).
Adjust qvm-clone tool and tests accordingly.
QubesOS/qubes-issues#2622
Enable 'qrexec' VM feature to wait for qrexec initialization - it is
required to call qubes.PostInstall service. If VM start fails, assume
there is no qrexec and drop that feature.
Since Admin API, qvm-ls takes a long time to complete. Therefore,
Corporate Headquarters commanded that a Enterprise Spinner is to be
implemented and mandated it's use unto us.
We take amusement from its endless gyrations.
Since migration to Admin API, qvm-ls no longer have list of all VM
properties in advance, so can't really validate fields list. Simply
assume that unknown columns are properties.
Don't terminate qvm-run on any SIGCHLD, check if the process we're
waiting for have finished.
Currently the only situation when it's broken is a test (which starts
additional process, whose SIGCHLD may be caught here), but lets do not
assume that much (starting only one process) about environment.
It is supported only from dom0, but it's still useful to have, to save
on simultaneous vchan connections (only waiting for MSG_DATA_EXIT_CODE).
This is especially important for Windows VMs, as qrexec-agent there have
pretty low limit on simultaneous connections (about 20).
Make qvm-run use it.
