Great to see virt-manager now makes it easy to enable 3D acceleration for Linux guests via virgl. However since only Linux guests have virgl drivers, 3D acceleration for Windows guests requires GPU passthrough.

It's a shame the blog post doesn't mention options such as Intel GVT. It appears that GVT works when launching qemu directly, but support via libvirt, virsh and virt-manager doesn't exist yet. Anyone aware of work towards enabling GVT via virt-manager?

Maybe this? https://wiki.archlinux.org/index.php...#Using_libvirt

I'll offer an unpopular opinion. Using virt-manager is way harder than using qemu directly. Editing virsh or virt-manager is mostly harder than editing direct qemu command. I just save the commands in script files and launch those. I don't know why people use virsh.

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.

Proxmox...

I was talking about QEMU.

I said slayerizer!

I was using QXL for windows, and got quite some comments below the video that people where impressed by the performance

When I first learned about the QXL option, I thought it offered some sort of video acceleration (like VirGL) or even 60Hz, but no, it didn't... (not even through a SPICE viewer)

Ha Ha Ha. Oh, of course, the problem is with me, and not the people who butcher grammar..

Well Proxmox's just a GUI for KVM/QEMU so it shouldn't be that hard to look at how they use it.

In that video you don't use QXL, you use vga vmware???
