Phoronix: QEMU's Assortment Of Virtual VGA/GPU Options & What To Pick For Desktop Virtualization

The virtual GPU/display landscape particularly for having accelerated guest graphics was once non-existent and then suffering for the open-source Linux virtualization stack around QEMU, but that is no longer the case. There are options these days to rival the GPU/display offerings of VirtualBox and VMware albeit to newcomers may not be so clear...

Is it possible to use -vga virtio (with OpenGL acceleration) outside X?

Also, there is a typo. Guest please find it.

I assume there's still no way of getting virgl set up in virt-manager?

[ihatemichael]

Why isn't -vga virtio the default?

Typo:

Cirrua VGA

Proxmox does support running Virtio-GPU for a VM and then accessing that display via the web interface as noVNC HTML5. Pretty sure there's no X involved on the host then, but I haven't tested if any form of acceleration is available that way.

Why? It is pretty trivial, just select virtio device and click 3D acceleration checkbox.

Last time I tried, it only worked with a "QEMU/KVM user session" - and that removes some other things that I need ( networking options, for example ).

Never tried system session, but on user session it work pretty fine for me.
Edit: Also I use Q35 and PCIe if it makes any difference.

I was using QXL for windows, and got quite some comments below the video that people where impressed by the performance, two years ago: https://www.youtube.com/watch?v=fyclA-_M-aA
