- for netvm it doesn't make sense, but instead of removing it (which
surely will break some code), make it always False
- when settings VM connections, uses_default_netvm is already loaded
- handle it properly during backup restore (really use default netvm,
istead of assuming it's the same as during backup)
Many drivers, including iwlwifi doesn't handle this well, resulting in
oopses etc. Also we're disabling PCI hotplug, which may be result in
more troubles here.
This reverts commit 2658c9a6e6.

This is very easy if the file/device is in dom0, so do it to avoid
cryptic startup error (`libvirtError: internal error: libxenlight failed
to create domain`).

There are problems with using sudo in early system startup
(systemd-logind not running yet, pam_systemd timeouts). Since we don't
need full session here, runuser is good enough (even better: faster).
On VM start, old qubesdb-daemon is terminated (if still running). In
practice it happen only at VM startart (shutdown and quickly start
again). But in that case, if the VM was started by root, such operation
would fail.
So when VM is started by root, make sure that qubesdb-daemon will be
running as normal user (the first user in group 'qubes' - there should
be only one).

Enable e820_host option for VMs with PCI devices (to allow VM kernel to
deal with address space conflicts). But add a property to allow
disabling it.

qrexec-daemon will start new processes for called services, which
include starting new DispVM, starting other required VMs (like backend
GPG VM). Having those processes as root leads to many permissions
problems, like the one linked below. So when VM is started by root, make
sure that qrexec-daemon will be running as normal user (the first user
in group 'qubes' - there should be only one).

On KDE5 native decoration plugin is used and requires special properties
set (instead of `_QUBES_VMNAME` etc).
Special care needs to be taken when detecting environment, because
environment variables aren't good enough - this script may be running
with cleared environment (through sudo, or from systemd). So check
properties of X11 root window.

This behaves better when running multiple VMs. If one need full CPU
power in some VM, it is always possible to increase vCPUs for this
particular VM.

1. wait=False isn't supportet together with localcmd (explicit, or
implicit via 'input') - qrexec-client refuses such combination
2. When using localcmd, qrexec-client exists as soon as the local command
terminates, not necessary remote. This may not be desired effect when
used with wait=True (the default), so do not use localcmd in such a
case
Found while debugging tests for qubes.USBAttach/qubes.USBDetach - with
wait=True broken, there were a lot of race conditions.

In some cases libvirt doesn't report error code at all. This probably
happens in some stage of domain startup/shutdown. Threat this the same
as domain not running.

We still can't support running HVM template and its VMs simultaneously
(easily), but still, have root-cow.img handled for HVM template, to
allow qvm-revert-template-changes.

In some (most) cases VM needs to be started to complete resize
operation. This may be unexpected, so make it clear and do not start the
VM when the user did not explicitly allow that.

When /var/lib/qubes/appvms is a mount point of ext4 filesystem, there
will be already 'lost+found' directory. Avoid this conflict.

The comment "calling VM have the same netvm" doesn't apply to:
- DispVM started from dom0 menu
- DispVM started from a VM with `dispvm_netvm` property modified
FixesQubesOS/qubes-issues#1334
When VM is shutting down it doesn't disconnect PCI frontend (?), so when
VM is destroyed it ends up in timeouts in PCI backend shutdown (which
can't communicate with frontend at that stage). Prevent this by
detaching PCI devices while VM is still running.

I had some issue with fstrim and the missing else had caused the code to continue and fail later with a non-descriptive error message. This commit makes the error message more descriptive and helpful.
This is workaround for missing libxl/libvirt functionality: QubesOS/qubes-issues#1426
Also it should improve system shutdown time, as this is the situation
where all the VMs are shutting down simultaneously.
