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).

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

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).
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.
* 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.
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.
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.

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.
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.
FixesQubesOS/qubes-issues#3055
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.
FixesQubesOS/qubes-issues#2974
When data block is smaller than 4096 (and no EOF is reached), python's
io.read() will call read(2) again to get more data. This may deadlock if
the other end of connection will write anything only after receiveing
data (which is the case for qubes.Filecopy).
Disable this buffering by using syscall wrappers directly. To not affect
performance that much, increase buffer size to 64k.

it.
