Since kernel 5.15, there is an issue with io_uring when used in
combination with CIFS [0]. Unfortunately, the kernel developers did
not suggest any way to resolve the issue and didn't comment on my
proposed one. So for now, just disable io_uring when the storage is
CIFS, like is done for other storage types that had problematic
interactions.
It is rather easy to reproduce when writing large amounts of data
within the VM. I used
dd if=/dev/urandom of=file bs=1M count=1000
to reproduce it consistently, but your mileage may vary.

When passing through an NVIDIA vGPU via mediated devices, their
software needs the qemu process to have the 'uuid' parameter set to the
one of the vGPU. Since it's currently not possible to pass through multiple
vGPUs to one VM (seems to be an NVIDIA driver limitation at the moment),
we don't have to take care about that.
Sadly, the place we do this, it does not show up in 'qm showcmd' as we
don't (want to) query the pci devices in that case, and then we don't
have a way of knowing if it's an NVIDIA card or not. But since this

- spice is not used (else the explicit ticket wins because it comes

- a local TPM state volume is used
- that local TPM state volume has a different volume id on the target
node (switched storage, volname already taken, ..)
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
not exist on the target node, migration will fail. if it exists by
chance, it might work albeit with a wrong spice ticket (new because of

have rather bad effects for users that did not setup some .link files

one would like to change that much in the first place...

Starts an instance of swtpm per VM in it's systemd scope, it will
terminate by itself if the VM exits, or be terminated manually if
startup fails.
Before first use, a TPM state is created via swtpm_setup. State is
stored in a 'tpmstate0' volume, treated much the same way as an efidisk.
It is migrated 'offline', the important part here is the creation of the
target volume, the actual data transfer happens via the QEMU device
state migration process.
Move-disk can only work offline, as the disk is not registered with
QEMU, so 'drive-mirror' wouldn't work. swtpm itself has no method of
moving a backing storage at runtime.
For backups, a bit of a workaround is necessary (this may later be
replaced by NBD support in swtpm): During the backup, we attach the
backing file of the TPM as a read-only drive to QEMU, so our backup
code can detect it as a block device and back it up as such, while
ensuring consistency with the rest of disk state ("snapshot" semantic).
The name for the ephemeral drive is specifically chosen as
'drive-tpmstate0-backup', diverging from our usual naming scheme with
the '-backup' suffix, to avoid it ever being treated as a regular drive
from the rest of the stack in case it gets left over after a backup for
some reason (shouldn't happen).

Since it is attached differently to a regular drive, adding PBS backing

KillMode 'none' is deprecated, and systemd loudly complains about that

This mode does two things differently, which we have to stop it from
doing:
* it sends SIGTERM right when the scope is cancelled (e.g. on shutdown)
-> but only to the "root" process, which in our case is the worker
instance forking QEMU, so it is already dead by the time this happens
* it sends SIGKILL to *all* children after a timeout
-> can be avoided by setting either SendSIGKILL to false, or
TimeoutStopUSec to infinity - for safety, we do both

QEMU warns us about this:
kvm: -chardev socket,id=qmp,path=/var/run/qemu-server/100.qmp,server,nowait: warning: short-form boolean option 'server' deprecated
Please use server=on instead
kvm: -chardev socket,id=qmp,path=/var/run/qemu-server/100.qmp,server,nowait: warning: short-form boolean option 'nowait' deprecated
Please use wait=off instead
kvm: -vnc unix:/var/run/qemu-server/100.vnc,password: warning: short-form boolean option 'password' deprecated
Please use password=on instead
The new syntax is backwards compatible to at least QEMU 4.0.
