[pve-devel] [PATCH qemu-server] api: fix 'use of uninitialized value' when checking vga type

[Dominik Csapak <d.csapak@proxmox.com>]

in our schema for 'vga' the type is optional, so a config like

 vga: memory=64

is valid. When checking the type we have to check if the type is defined
before accessing it.
