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

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.

required for that to be understood is guaranteed to be available with
pve-manager 7.2-13 or newer, as that raised the versioned dependencies
respectively.
This hedges against a migration from a node with newer version to one
with older version, the effects would be basically that the name
argument in a cloudinit section would override the current one, as the
old parser interprets it as belonging to the main section, not the
cloudinit section.
We normally are cautious with removing such guards, and communicate
stricter requirements than we check, to safeguard users with a certain
ignorance or willingness to care for proper and periodic timely
upgrades.
But due to:
- PVE 7 being EOL since a few months
- PVE 7.2 being EOL for well over a year
- the documented requirement to upgrade to latest PVE 7.4 before an

amd_sev: es,no-debug=1,kernel-hashes=1
kernel-hashes, reduced-phys-bits & cbitpos correspond to the variables

kernel-hashes=1 adds kernel hashes to enable measured linux kernel

reduced-phys-bios and cbitpos are system specific and are read out by
the query-machine-capabilities c program and saved to the
/run/qemu-server/host-hw-capabilities.json file. This file is parsed
and than used by qemu-server to correctly start a AMD SEV VM.
type=std stands for standard sev to differentiate it from sev-es (es)
or sev-snp (snp) when support is upstream.
QEMU's sev-guest policy gets calculated with the parameters no-debug
& no-key-sharing. These parameters correspond to policy-bits 0 & 1.
If type is 'es' than policy-bit 2 gets set to 1 to activate SEV-ES.
Policy bit 3 (nosend) is always set to 1, because migration features
for sev are not upstream yet and are attackable.
SEV-ES is highly experimental since it could not be tested.
