virtio-vga is vga compatible based on [1]. it should be better than standard vga. [1] - https://www.kraxel.org/blog/2019/09/display-devices-in-qemu/#VGA
Additional information from Gerd: virtio-vga support 8MB vram for VGA compatibility. It will support high resolution (higher than FullHD) only when having drivers installed. As for linux guests, they have the drivers. For windows, it will require installing the virtio-win drivers.
(In reply to Liran Rotenberg from comment #1) > For windows, it will require installing the virtio-win drivers. That's the more tricky part - that virtio-vga should be compatible with standard vga in case the drivers are missing But since it requires more testings, we will default to standard vga now (as, e.g., libguestfs did) and we can reevaluate this once we have a better picture of how it works without drivers
We are past 4.5.0 feature freeze, please re-target.
let's review again
The scope of this one: change vga to virtio-vga "behind the scenes" and make sure that: 1. it works fine without virtio drivers on Windows (should have backward compatibility with vga) 2. that we won't unplug the device when correlating the reported devices and the ones we have in the database (that means not to add another type of a video device)
