regression introduced with commit a85ff91b
previously we set $target to undef if it's localnode or localhost, then
we check if node exists.
with regression commit, behaviour changes as we do the node check in
else, but $target may be undef. this causes an error:
no such cluster node ''

to achieve this we have to add 3 new scsihw addresses since lsi
controllers can only hold 7 scsi drives
we go up to 31, since this is the limit for virtio-scsi-single devices
we have reserved (we can increase this in the future)
to make it more future proof, we add a new pci bridge under pci
bridge 1, so we have to adapt the bridge adding code (we did not
need this for q35 previously)
impact on live migration:
since on older versions of qemu-server we do not have those config
settings, there is no problem from old -> new
new->old is not supported anyway and this breaks so that
the vm crashes and loses the configs for scsi15-30
(same behaviour as e.g. with audio0 and migration from new->old)
tested with 31 scsi disk on
i440fx + virtio-scsi
i440fx + lsi
q35 + virtio-scsi
q35 + lsi
with ovmf + seabios

The package will be used for custom CPU models as a SectionConfig, hence
the name. For now we simply move some CPU related helper functions and
declarations over from QemuServer to reduce clutter there.
Exports are to avoid changing all call sites, functions have useful
names on their own.

This is the guarantee that this call operates on it's created config.
A VMID cannot be reused afterall. So only remove the guarantee at the

* query_understood_cpu_flags returns all flags that QEMU/KVM knows about
* query_supported_cpu_flags returns all flags that QEMU/KVM can use on
this particular host.
To get supported flags, a temporary VM is started with QEMU, so we can
issue the "query-cpu-model-expansion" QMP command. This is how libvirt
queries supported flags for its "host-passthrough" CPU type.
query_supported_cpu_flags is thus rather slow and shouldn't be called
unnecessarily.
Note that KVM and TCG accelerators provide different expansions for the
"host" CPU type, so we need to query both.
Currently only supports x86_64, because QEMU-aarch64 doesn't provide the
necessary querying functions.

wrap around code which can possibly fail in evals to handle them
gracefully, and log errors.
note: this results in a change of behavior in the API. since errors
are handled gracefully instead of "die"ing, when there is a pending
change which cannot be applied for some reason, it will get logged in
the tasklog but the vm will continue booting regardless. the
non-applied change will stay in the pending section of the
configuration.

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

This reverts commit c5151cb8bb5f919c9e621065224c3d455b60f833 which is
a revert of the wrongly done revert of
commit e2414e73ce75893a143dc32cf6a4e58159cc25ff.
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.
