[pve-devel] [PATCH qemu-server 07/19] machine: add default_machine_for_arch() helper

[Fiona Ebner]

There are already other places where 'aarch64' and 'x86_64' are
checked to be the only valid architectures, for example, the
get_command_for_arch() helper, so the new error scenario for an
unknown arch should not cause any regressions.
