It wasn't possible to use QubesArgumentParser(vmname_nargs=...) for
optional domain list - the option forced usage of either --all or
explicit domain list.
When starting a VM with --cdrom=some-vm:/some/path/to.iso, it can be
started only when loop device matching the path is available. For now,
add naive waiting (while ... sleep(1)) for it. Later it might worth
converting it to events handling.
This is to match core-admin API. Logically it could be a property not a
method (as other things like usage or size), but it is already defined
(and used in various places) as a method in core-admin, so lets don't
change the API right now.
* qubesos/pr/44:
Fix style else-return
tests: update qvm-template-process and qvm-remove tests
Add --force to manpage.
Avoid cloning installed_by_rpm
Print vm list before prompt
Use --force instead of --yes
Toggle installed_by_rpm in template tool
Fix error message grammar
Add --yes option and confirm prompt.
Make use of better security of Qubes 4.x by using HVM by default. If
some VMs are incompatible with it (like MirageOS based), user can always
switch it to PV manually later.
This restores Qubes R3.2 behavior
Before this patch, the following:
qvm-run -p sys-firewall 'echo -e "\e[0;46mcyan!" >&2' | wc -l
leaks the escape sequences through to the dom0 terminal via stderr,
in this case demonstrated by the ability to change the text color while
it should be fixed to red.
This can also be abused with xterm reporting sequences to cause input
to be sent to the dom0 terminal. This is potentially a security issue.
The main process sometimes sets fd 1 to O_NONBLOCK, and since in the
terminal case fd 0 and 1 are the same fd, this also results in fd 0
being non-blocking, causing qvm-run to crash with EAGAIN.
So just make the code work for both blocking and non-blocking stdin.
When some VM timeout on shutdown, the tool will try to kill all of them,
but at this point some of them may be already powered off (not all
hanged during shutdown, but only some). Handle this
situation instead of crashing. And add appropriate test.
Do not crash if the other object is completely different type. Return
False ("unequal") instead.
This crashed preparing list of devices in qubes-vm-boot-from-device.

If EOF is reached on tar's stderr, stop reading it, even if didn't found
expected data. Log this event.
This may happen when tar output some fatal error, instead of filelist.
os.path.splitext fails on path without proper file base name, like
'/something/..000'. Use plain string methods (rsplit).

Packages had missing dependency on python-dbus. Since DBusHandler isn't
used anywhere, drop it, instead of introducing more dependencies.

vm.get_power_state() have specifically documented 'NA' state for cases
when it's unable to get VM's power state. Use this when qrexec policy
forbid checking it.

1. Output of `losetup` command contains `\n` - strip it.
2. Provide read-only option - if device info hasn't propagated to qubesd
yet, it will not be set automatically.

First, TemplateVM is not used anymore (see previous commit). Second,
don't harcode on client side that "only TemplateVM can be a template for
any VM" (which actually isn't true: AppVM can be a template for DispVM).
Very few calls at client side really needs VM class name. So, even in
non-blind mode use just QubesVM class, to avoid strange cases depending
on blind mode being enabled or not. Then, have VM class name in 'klass'
property. If known at object creation time, cache it, otherwise query
qubesd at first access.
It may happen that when client handle the event, domain no longer
exists. This is for example common for DispVMs, which get removed just
after shutdown.
This will cause some events to be dropped, but one can enable blind
mode, to get them anyway (because it will not cause KeyError, even if
domain is already removed).
QubesOS/qubes-issues#3100
This allows to perform actions on objects (VM, storage etc), without
listing them. This is useful when calling VM have minimal permissions
and only selected actions are allowed.
This means that app.domains['some-name'] will not raise KeyError, even
when domain do not exists. But performing actual action (like
vm.start()) will fail in that case.
Booting a VM from cdrom require attaching the device before VM startup,
which is possible only in persistent mode. But for qvm-start --cdrom
adding a cdrom only temporarily, use new update_persistence() function
to convert the assignment to temporary one.

Abort tar process after extracting requested files - do not parse the
archive until the end (possibly tens of GB later).
FixesQubesOS/qubes-issues#2986
This may be confiusing, for example one may think that
`qvm-prefs --unset vmname netvm` will make vmname network-disconnected.
This type of mistakes may have severe security consequence, so better
drop those option names.

Add option to uniformly start new DispVM from either VM or Dom0. This
use DispVMWrapper, which translate it to either qrexec call to $dispvm,
or (in dom0) to appropriate Admin API call to create fresh DispVM
first.
This require abandoning registering --all and --exclude by
QubesArgumentParser, because we need to add --dispvm mutually exclusive
with those two. But actually handling those two options is still done by
QubesArgumentParser.
This also updates man page and tests.
