[pve-devel] [PATCH qemu-server v8 1/2] add new public get_default_vga_type function

[Aaron Lauterer]

we resolve missing parameters if necessary to make it easier to call
from another module where we likely only have the VM config ready.

changes since
v7:
* rebased
v6:
* instead of making get_vga_properties and extract_version public, we
create the new get_default_vga_type function and only make it public.
