[pve-devel] [PATCH qemu-server v2] use machine version in vga default type selection

[Thomas Lamprecht]

If we get an VM machine older than 2.9 we use the old selection
expression for the VGA type. This allows to live migrate VMs to PVE
5.0 from beta 1 and PVE 4.4 again.

changes v1 -> v2:
* renamed from "add workaround for pve 4.4 to 5.0 live migration"
* move code handling this to PVE 5.0, as this is how we do it normally
* obtain from touching the config, this is to much of a hack
