which is the case for passed-through disks. The qemu_img_format()
function cannot correctly handle those, and it's not safe to assume
they are raw (it's most likely, but not guaranteed), so just use the
storage method for the format like it was done before commit
efa3aa24 ("avoid list context for volume_size_info calls"). This will
use 'qemu-img info' to get the actual format.

With the recent pve-storage commit d70d814 ("api: fix get content call response
type for RBD/ZFS/iSCSI volumes"), the volume_size_info call for RBD in
list context is much slower than before (from a quick test, about twice as long
without snapshots, even longer with snapshots and untested, but when using an
external cluster with image not having the fast-diff feature, it should be worse
still) and thus increases the likelihood to run into timeouts here.
None of the callers here actually need the more expensive call, so just
avoid calling in list context.

While, usually, the slot should match the ID, it's not explicitly
guaranteed and relies on QEMU internals. Using the numerical ID is
more future-proof and more consistent with plugging, where no slot
information (except the maximum limit) is relied upon.

in some nvidia grid drivers (e.g. 14.4 and 15.x), their kernel module
tries to clean up the mdev device when the vm is shutdown and if it
cannot do that (e.g. becaues we already cleaned it up), their removal
process cancels with an error such that the vgpu does still exist inside
their book-keeping, but can't be used/recreated/freed until a reboot.
since there seems no obvious way to detect if thats the case besides
either parsing dmesg (which is racy), or the nvidia kernel module
version(which i'd rather not do), we simply test the pci device vendor
for nvidia and add a 10s sleep. that should give the driver enough time
to clean up and we will not find the path anymore and skip the cleanup.
This way, it works with both the newer and older versions of the driver
(some of the older drivers are LTS releases, so they're still
supported).

instead of using the mdev uuid. The nvidia driver does not actually care
that it's the same as the mdev, and in qemu the uuid parameter
overwrites the smbios1 uuid internally, so we should have been reusing
that in the first place.

AFAICT, previously, errors from swtpm would not show up in any logs,
because they were just printed to the stderr of the daemonized
invocation here.
The 'truncate' option is not used, so that the log is not immediately
lost when a new instance is started. This increases the chance that
the relevant errors are still present when requesting the log from a
user.
Log level 1 contains the most relevant errors and seems to be quiet
for working-as-expected invocations. Log level 2 already includes
logging full TPM commands, some of which are 1024 bytes long. Thus,
log level 1 was chosen.

The guest will be running, so it's misleading to fail the start task
here. Also ensures that we clean up the hibernation state upon resume
even if there is an error here, which did not happen previously[0].

The target of the drive-mirror operation is opened with (essentially)
the same flags as the source in QEMU, in particular whether io_uring
should be used is inherited.
But io_uring currently causes problems in combination with certain
storage types, sometimes even leading to crashes (LVM with Linux 6.1).
Just disallow live cloning of drives when the source uses io_uring and
the target storage is not ready for it. There is one exception, namely
when source and target storage are the same. In that case, just assume
it will keep working for the target.
Migration does not seem to be affected, because there, the target VM
opens the images with the checked aio setting and then NBD exports of
those are used as the targets for mirroring.
It can be that the default determined for the source is not what's
actually used, because after a drive-mirror to a storage with a
different default, it will still use the default from the old storage.
Unfortunately, aio doesn't seem to be part of the 'query-block' QMP
command's result, so just tolerate this edge case.
The check can be removed if either
1. drive-mirror learns to open the target with a different aio setting
or more ideally
2. there are no more bad storages for io_uring.

Previously, changing aio would be applied to the configuration, but

Since commit 9b6efe43 ("migrate: add live-migration of replicated
disks") live-migration with replicated volumes is possible. When
handling the replication, it is checked that all local volumes
previously detected as replicatable are actually replicated. So the
check if migration with snapshots is possible can just allow volumes
that are detected as replicatable.
Note that VM state files are also replicated.
If there is an invalid configuration with a non-replicatable volume or
state file and replication is enabled, then replication will fail, and
thus migration will fail early.
Trying to live-migrate to a non-replication target (needs --force)
will still fail if there are snapshots, because they are (correctly)
detected as non-replicated.

The 'nbd-server-add' QMP command has been deprecated since QEMU 5.2 in
favor of a more general 'block-export-add'.
When using 'nbd-server-add', QEMU internally converts the parameters
and calls blk_exp_add() which is also used by 'block-export-add'. It
does one more thing, namely calling nbd_export_set_on_eject_blk() to
auto-remove the export from the server when the backing drive goes
away. But that behavior is not needed in our case, stopping the NBD
server removes the exports anyways.
It was checked with a debugger that the parameters to blk_exp_add()
are still the same after this change. Well, the block node names are
autogenerated and not consistent across invocations.
The alternative to using 'query-block' would be specifying a
predictable 'node-name' for our '-drive' commandline. It's not that
difficult for this use case, but in general one needs to be careful
(e.g. it can't be specified for an empty CD drive, but would need to
be set when inserting a CD later). Querying the actual 'node-name'
seemed a bit more future-proof.

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.

When rolling back to the snapshot of a VM that includes RAM, the VM
gets started by the rollback task anyway, so no additional start task
is needed. Previously, when rolling back with the start parameter and
the VM snapshot included RAM, a start task was created. That task
failed because the VM had already been started by the rollback task.
Additionally documented this behaviour in the description of the start
parameter
