This change introduces a complete rewrite of the argument parser for the `qvm-pool` tool.
As suggested by @marmarek in qubes-issues#5407, the goal is to be consistent with other tools such as `qvm-device`, `qvm-volume` etc.
(resolvesQubesOS/qubes-issues#5407)
If the VM is powered off shortly after startup, it may happen that
qubes.SetMonitorLayout would start it again. Avoid this by using
autostart=False argument to run_service() function.
Note that there is a vm.is_running() check at the beginning of the
function already, but if it happens while the VM is cleaned up, it may
still report that it's running, but at the time of run_service() call it
is not.
Previous commit introduced protection against uncommon (potentially
malicious) compression filters. This breaks restoring backups made with
a custom compression filter. Add an option to override this check, by
naming compression filter to use explicitly.

Add support for importing volume data with qvm-volume tool.
This could be also used to clear volume by issuing:
qvm-volume import --no-resize some-vm:private /dev/null
QubesOS/qubes-issues#5192
Reinstalling template is a recommended way to get it back to a clean
state after potential compromise. In that case it is essential to
discard any persistent storage of old template, as it could be used by
the attacker to re-compromise it after reinstall.
Do this similar as root volume is overridden - via volume import
function.
FixesQubesOS/qubes-issues#5192
Addresses review comments, specifically:
* updates qvm-clone tests to handle ignore_errors option
* adds manpage reference to new --ignore-errors option
* trims line length in qvm-clone changes
All tests should now be passing, including the new qvm-clone
functionality.
Specify compression explicitly in the backup profile, not only when
requested with --compress or --compress-filter.
This will allow to disable compression with --no-compress option, as the
default if no compression is specified in the profile is to use gzip.
FixesQubesOS/qubes-issues#4803
Since no output from VM is passed (and even if it would, it's redirected
to /dev/null), there is no need to switch output color.
This fixes the case when qvm-run is started in background - the color
change would affect further shell output.
FixesQubesOS/qubes-issues#4808
Pylint complains that main() is too long and that's indeed true. Factor
out single process call (together with all the prepartion) into separate
function and keep only common code in main().
Print some error even without --pass-io, otherwise the only way to learn
the failure is checking $?, as no other visual sign is there.
FixesQubesOS/qubes-issues#4533
qubes.VMShell service, used by qvm-run, expects the command on the first
input line. Previously, when --localcmd was used, the command wasn't
written anywhere and the local command was connected directly to
qubes.VMShell service. And the first line of its output was interpreted
as a command.
Fix this by starting the local command separately, after sending the
command to qubes.VMShell service.
While at it, unify handling shell command and service calls in the process.
vm.run_service(..., localcmd= ) isn't that useful in general case,
because for qubes.VMShell the caller first need to send the command
before starting local process. Since the qvm-run tool needs to implement
manual starting localcmd anyway, don't use localcmd= run_service's
argument at all to unify calling methods.
There is slight behavior change: previously localcmd was started only
after establishing service connection (for example only if qrexec policy
allows), now it is started in all the cases.

By definition StandaloneVM is not linked to the template. Creating one
from a template is a clone operation. It's already possible using
qvm-clone tool, but it's logical to do that using qvm-create tool too.
This was the case in R3.2 too.
While adding this special case, skip cloning private volume, to preserve
behaviour of TemplateBaseVMs which do not inherit private volume either.
FixesQubesOS/qubes-issues#3793
If file to be imported is larger than the default root volume, resize
the volume first. It might be also a good idea to shrink it when needed,
but currently the backend refuse it.

* windows-tools:
doc: add info what properties are inherited from template
Add 'gui-emulated' feature
qvm-start-gui: fix handlign rpc-clipboard feature
Add an explicit method for forcing emulated VGA output. Previously it
was possible only by removing `gui` feature (setting it to false had a
different effect), or enabling debug mode.
Using lack of a feature as a third state was a bad idea.

Do not crash if qubesd restart exactly the moment event handler was
called.
Event listener properly handle qubesd restarts (reconnects), but exists
if any handler raise an exception. Avoid this by logging such exceptions
but not propagating them.
There was such option on Qubes 3.2, so add it here too. This is
especially useful for kernel package - preun script use it to verify if
given kernel isn't needed anymore.
* improved-tools-messages:
tools: suppress full traceback in console tools
tools: add SubParsersHelpAction, which include subcommands details in --help
Right now Admin API backend will refuse to shrink volume anyway, but
we're planning to relax this restriction. Make sure the client side
(qvm-volume tool here, GUI VM settings already have this in place) will
employ appropriate safety check.
QubesOS/qubes-issues#3725
If needs to be extended - do it before import. If needs to be reduced -
after. This way, if data import fails for any reason, previous data
won't be destroyed (truncated).
Also, convert error on shrinking volume to a warning, as it doesn't break
the template (just leave it with bigger disk than needed). Currently all
storage pool implementations refuse to shrink a volume (but it may
change in the future).
QubesOS/qubes-issues#3169
QubesException class is used with meaningful messages and should be ok
to use it directly as error message. For other exceptions, still use
full traceback (most likely a bug somewhere, not user error).
FixesQubesOS/qubes-issues#3610
Don't print None value as 'None' string, but as empty one (same as at
API level). Otherwise it is indistinguishable from VM named 'None', or
same string property value.
This is especially important on LVM thin pool, where space after
removing the file needs to be given back to the pool, to be reused for
other volumes (for example this template).
qvm-start-gui lifecycle should be bound to X server lifecycle. It should
be restarted when user logoff and login again, at least to start
gui-daemons again.
Do that by opening a connection to X server and reacting to breaking
that socket.

I don't know if any template currently hits this code path, even the
fedora-26-minimal root.img is large enough to be split into multiple
parts. Maybe Arch Linux?

'qvm-run --dispvm' cannot easily make a separate qubes.WaitForSession
call. Instead, if --gui is active, pass the new WaitForSession argument
to qubes.VMShell, which will do the equivalent.
The unit tests have been copied (in slightly adapted form) from commit
a620f02e2aFixesQubesOS/qubes-issues#3012ClosesQubesOS/qubes-core-admin-client#49
In core-admin matching collections are real dicts, so clone this API
behaviour here too. Specific changes:
- iteration yields keys, not values
- implement values and items methods
Additionally fix keys method, it was broken on python2 (list have no
copy method).
