When the VM is running, after deleting the tpmstate from the
configuration, the TPM drive will still be active, because it is used
by swtpm and QEMU will still have the TPM socket.
Also, a subsequent live migration will fail, because the
commandline for the target instance does not match the one for the
source:
> kvm: Unknown ramblock "tpm-ppi", cannot accept migration
For efidisk, hotunplug would already fail with

but it's better to catch this early and queue the change as pending
instead.

For PBS, templates are started in 'prelaunch' mode for backup and the
same can be done for VMA for consistency.
Signed-off-by: Fiona Ebner <f.ebner@proxmox.com>
Previously, the template's configuration was used as-is for the rest
of handling the VM start even if config_to_command() uses a minimized
configuration to build the command. This can lead to issues with a
network device with the 'link_down' flag set, because the network
device will not be present, but the start handling will still issue a
QMP command for it, leading to a failed backup operation.
Use the minimized configuration for the whole start-up handling to
avoid such issues.
Use the special QemuConfig::NoWrite class to safeguard against
accidentally writing out the temporarily modified config.

A failure during enforce_vm_running_for_backup() would result in
restore_vm_power_state() not being called, but the VM might already
have been started before the failure. In particular, this could happen
in the context of bug #6007 [0], where the 'set_link' QMP command
fails right after VM start.
If the failure happens before successful start, there will be an
additional error message issued by restore_vm_power_state() (that the
VM is not running). This could be avoided by returning early if the VM
is not running anymore, but that would mean not warning about it in
other scenarios where it is not expected and keeping track of whether
the VM was actually started or not does not seem to be worth it just
for avoiding that error message in this edge case.

Fixes device hotplug in combination with QEMU 9.2.
QEMU commit be93fd5372 ("qdev-monitor: avoid QemuOpts in QMP device_add")
notes:
> This patch changes the behavior of QMP device_add but not HMP
> device_add. QMP clients that sent incorrectly typed device_add QMP
> commands no longer work. This is a breaking change but clients should be
> using the correct types already.
The qemu_deviceadd() helper does not have the required type
information right now, so switch to using HMP, which still behaves the
same when passing a device commandline string. QEMU commit be93fd5372
fixes passing in complex properties via JSON, but the qemu_deviceadd()
helper never uses any such, as it already only received a string (and
naively split it up).
Use HMP for 'device_del' too, simply to keep the qemu_deviceadd() and
qemu_devicedel() helpers consistent.
Switching back to QMP using the correct types in the JSON can still be
done later. Unfortunately, 'qmp-query-schema' does not provide
device-specific types, so another way is needed.
A timeout of 25 seconds is used rather then relying on the low default
like before, since device plug operations require actions by the guest
kernel and might require IO. Device plug is often an interactive
operation, so a too high timeout could lead to bad UX. For now stay a
few seconds under the default timeout of 30 seconds of our web UI's
API request handler. Should specific devices need a higher timeout, it
can still be increased further for them in the future.

While no problem is known with having an empty machine string in the
configuration and it was already possible setting an empty machine
manually via 'qm set', the behavior changed because of commit 919e69d0
("machine: add check_and_pin_machine_string() helper") and there is
potential for problematic edge cases. Restore the previous behavior.
Pinning is also required when there is no given machine type, so the
call to check_and_pin_machine_string() should stay unconditional.
For update, pinning was recently added by commit 7a9570f3 ("api:
update vm config: pin machine version when switching to windows os
type"), so bring that in-line with the behavior for create too.
Another idea would've been to just return the default machine in
check_and_pin_machine_string(), but that would also be a change in
behavior. In particular, the default depends on the arch, so an empty
machine type will pick the default machine for the currently
configured arch even when the arch is later changed.
