[pve-devel] [PATCH qemu-server v7 1/4] QemuServer: add new public get_default_vga_type function

[Aaron Lauterer]

by moving that part out of get_vga_properties.

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 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.
