instead of writing the config after every change, we can do it once for
all the changes in the end to avoid redundant i/o.
we also don't need to load_config after writing fastplug changes.

Do the same as for the "create" case, only trigger the "start after
create/restore" task after the locked "realcmd" was done. Else, the
start can never succeed, it also acquires a lock, but restore only
release it once outside of realcmd.

QEMU usually only prints warnings and errors and stays silent otherwise,
so it makes sense to just log all of it's output.
Prefix it with '[<target_hostname>]' to indicate that the output is
coming from the remote node, so users know where to search for the
error.
Side effect is that the 'VM start' task created by the migration will
now show the "QEMU:" prefix, but it's still very readable IMHO.

By default run_command prints the entire commandline executed when an
error occurs, but QEMU and our migrate command are not only
uninteresting to the user[*] but also annoyingly long. Hide them and only
print the exit code.
[*] Especially our migrate command, since it can't be manually executed
anyway. QEMU's commandline *might* contain something interesting, but is
so long that it's tricky to parse anyway, any a user can always call 'qm
showcmd --pretty'.

Split out 'update_disksize' from the renamed 'update_disk_config' to
allow code reuse in QemuMigrate.
Remove dots after messages to keep style consistent for migration log.
After updating in sync_disks (phase1) of migration, write out updated
config. This means that even if migration fails or is aborted in later
stages, we keep the fixed config - this is not an issue, as it would
have been fixed on the next attempt anyway, and it can't hurt to have
the correct size instead of a wrong one either way.

if the user set a device as hostpci with the 'shorthand' syntax:
hostpciX: 00:12
we ignored it on starting and showcmd and continued.
Since the user explicitly wanted to passthrough a device, we now check
if there is actually a device with that id
for explicitly configured devices (00:12.1), we did not check if it exists,
but the kvm call failed with a non-obvious error message
now we always call 'lspci' from SysFSTools to check if it actually exists,
and fail if not. With this, we can drop the workaround for adding
'0000' if no domain was given, since lspci does it already for us
this fixes#2510, an issue with using mediated devices where the users did not have
the domain in the config, since we forgot to add the default domain there
the only issue with this patch is that it changes the behaviour of
'showcmd' slightly, as in now, we die if the device was explicitly
given, but did not exists (we showed the commandline, now we fail)
this also slightly changes the commandline for qemu (adding always
the domain), which is not a problem since we cannot live migrate
or snapshot such vms, but we have to adapt the tests

some storage backends have bigger granularity than the default 128k
size from the EFIVARS template file, so we actually need to poll the
real created disk size, as it will be used to create the target
volume for local storage migration on running VMs, if it's to small
the target will be to small and migration will fail.
Just a fix for newly created EFIDISKS, for others we need to rescan
the size after we've got the migrate lock and write the updated info
out, so that the target node has the correct one (protected from
migrate lock).

Sometimes, a user wants to remove the 'suspended' state without
resuming the vm from that state. Since the vm is locked with
'suspended', this was not possible without help from root@pam
This patch allows to delete the vmstate and the suspended lock and
related config entries with it. The user still has to have the right
priviliges and the vm cannot be 'protected' for this to work

With our QEMU 4.1.1 package we can pass a additional internal version
to QEMU's machine, it will be split out there and ignored, but
returned on a QMP 'query-machines' call.
This allows us to use it for increasing the granularity with which we
can roll-out HW layout changes/additions for VMs. Until now we
required a machine version bump, happening normally every major
release of QEMU, with seldom, for us irrelevant, exceptions.
This often delays rolling out a feature, which would break
live-migration, by several months. That can now be avoided, the new
"pve-version" component of the machine can be bumped at will, and
thus we are much more flexible.
That versions orders after the ($major, $minor) version components
from an stable release - it can thus also be reset on the next
release.
The implementation extends the qemu-machine REGEX, remembers
"pve-version" when doing a "query-machines" and integrates support
into the min_version and extract_version helpers.
We start out with a version of 1.
