[pve-devel] [PATCH qemu-server 6/6] vm start: add warning about deprecated machine version

[Fiona Ebner <f.ebner@proxmox.com>]

While there already is a warning from QEMU proper, that one is not
visible as a task warning and it's not straightforward to make it be
one, because QEMU is started inside a run_fork(). It's also more
future-proof to have the detection explicit on our side and the
documentation can be referenced.
