when a vm is configured to use a physical cd rom drive but there is no
such drive a cryptic "uninitialized value" error is thrown. this is
due to `$path` being undefined in `sub print_drive_commandline_full`.
warn that no cd rom drive is available instead.
note that the error was cosmetic as the vm would start just fine.

Since we can now differentiate between 'suspended' and 'suspending',
it is possible to ignore the 'suspended' lock when destroying a VM.
It shouldn't matter whether the VM is locked because of hibernation
when you want to remove it. Therefore we can safely ignore the lock.
When $d->{'pci_bridge'}->{devices} is undef, @-dereferencing it will
die with:
> Can't use an undefined value as an ARRAY reference
This can happen (at least) when the VM is in 'prelaunch' state. The
QAPI definition for '@PciBridgeInfo' also declares the 'devices'
member as optional.
Before commit 721624b ("collect device list for nested pci-bridges"),
there was no issue, because $d->{'pci_bridge'}->{devices} was used in
foreach, so auto-vivified if undef.

the fix for the recently introduced requirement of loading the VM config while
migrating was incomplete, since the vmlist node value could already be out of
date by the time load_config is called.
extend the fallback behaviour even further, by doing the following sequence:
- try regular load_config (likely case, rename already fully processed)
- if it fails, get node from vmlist, and load_config using that
- it that fails, invalidate the PVE::Cluster cache, retry regular load_config

it's not deterministic whether the rename/move of the VM config
triggered on the source side of a migration is already visible on the
target side when vm_resume is executed. check the vmlist for the node
where the config is currently located if $nocheck is set - it is now
needed to add the forwarding DB entries to the bridge.
this fixes an issue on busier or slower clusters, where pmxcfs hasn't

remote migration uses a websocket connection to a task worker running on
the target node instead of commands via SSH to control the migration.
this websocket tunnel is started earlier than the SSH tunnel, and allows
adding UNIX-socket forwarding over additional websocket connections
on-demand.
the main differences to regular intra-cluster migration are:
- source VM config and disks are only removed upon request via --delete
- shared storages are treated like local storages, since we can't
assume they are shared across clusters (with potentical to extend this
by marking storages as shared)
- NBD migrated disks are explicitly pre-allocated on the target node via
tunnel command before starting the target VM instance
- in addition to storages, network bridges and the VMID itself is
transformed via a user defined mapping
- all commands and migration data streams are sent via a WS tunnel proxy
- pending changes and snapshots are discarded on the target side (for
the time being)

In theory we can have a config with netX records that do not specify
a `macaddr` property, we just auto-generate on in config2cmd for
startup transitively, but don't save that explicitly back to the
config; so while we could parse the /proc/$pid/cmdline or try to get
the info from QMP (not fully straight forward) it seems rather a
hassle; especially if one has in mind that this cannot happen via the
API FWICT; as there a "deletion" *saves* a newly auto generated value
out to the config, same with clone of a VM and restore of a backup.
So, in basically all reasonable cases we got the `macaddr` available,
but if we don't it makes no sense to add a FDB variable for a *newly*
generated one by the parse_net call, as the VM won't use that (well,
at least if one doesn't get "lucky" and it randomly re-generates the
same as on startup), so allow telling parse_net to skip auto
generating MACs and use that in the add-fdb-entries helper

because the target node will then mis-interpret the tpmstate0 line as
spice ticket and set it accordingly. if the old tpm state volume ID does

As that change affects systemds predictable interface naming[1],
e.g., by going from a previously `ens18` name to `enp6s18`, it may
have rather bad effects for users that did not setup some .link files
to enforce a specific naming by an more stable information like the
NIC's MAC-Address
The alternative would be making the preferred mode of hotplug an
option like `hotplug-mode=<acpi|pcie>`, but it does not seems like
one would like to change that much in the first place...
Note the changes to the tests and especially the tests with q35
machines that did not change.

this allows a user to set a drive to 'read-only'. This can be useful
if a disk should not be written to, or if the backing file/source is
not writable (like a mapped pbs backup to /dev/loopX).
the option is named 'ro', to achieve consistency with containers
while this could also be achieved by setting 'snapshot=1', this would
create a temporary file in /var/tmp which can get quite big.

ovmf with SMM enabled will not boot on i440fx (hangs on graphics
initialization), so load the non SMM variant.
should be no issue regarding live-migration since it never worked with
this anyway.
adapts the test and adds one with q35

fix the classic indentation error on `additionalProperties` in the
main QEMU API
drop some not so useful empty lines to avoid making rather huge
methods even bigger (more intimidating, less on screen to grasp the
full picture).

swtpm may take a little bit to daemonize, so the pidfile might not be
available right after run_command. Causes an ugly warning about using an
undefined value in a match, so wait up to 5s for it to appear.
Note that in testing this loop only ever got to the first or second
iteration, so I believe the timeout duration should be more than enough.
Also add a missing 'usleep' import, 'usleep' was used before but never
imported, apparently the other case never got triggered...

QEMU doesn't know about the tpmstate, so 'do_snapshots_with_qemu' should
never return true in that case. Note that inconsistencies related to
snapshot timing do not matter much, as the actual TPM data is exported
together with other device state by QEMU anyway.

`properties` is a bit ambiguous and as we have scope and start
runtime properties in the same scope it's good to avoid that
ambiguity.

on vm start, we reserve all pciids that we use, and
remove the reservation again in vm_stop_cleanup
first with only a time-based reservation but after the vm is started,
we reserve again but with the pid.
for this, we have to move the start_timeout calculation above the
hostpci handling.
also moved the pci initialization out of the conf parsing loop
so that we can reserve all ids before we actually touch any of them
while touching the lines, fix the indentation
this way, when a vm starts with a pci device that is already configured
for a different running vm, will not be started and the user gets
the error that the device is already in use
