[Users] desktop virtualization and GPU support
Hi, Currently we have a customer who would like to migrate to a thin-client virtual desktop environment. What is the status for GPU support in ovirt? Is 1:1 or 1:4 possible, where we'd attach a single GPU to each VM or one GPU to 4 VM's like in Citrix of VMWare? If we don't add GPU's will the desktops be usable at all? Thanks in advance, Jorick Astrego Netbulae B.V.

We were looking at this card: It's just for a couple of users that need GPU, the rest we can arrange with terminal server without GPU. http://hothardware.com/News/AMD-Sets-Its-Eyes-On-New-GPU-Virtualization-Mark... AMD's Citrix and VMWare support uses a mode called GPU Passthrough. In both cases, the software allows a virtual machine to directly access a GPU. In this use-case, GPUs and users are mapped in a 1:1 model, with one card dedicated to each client. It's also possible for Xenserver to create virtualized GPUs, with up to four users per card. The implication from AMD's presentation is that Citrix is a bit farther along than VMWare as far as supporting various GPU configurations, and that Remote FX is the most mature solution overall.

--=-ox/l2FVLyJfvBWfBsjuq Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable Hi, I'm afraid that none of these cards will work. IIRC it was explained for nVidia approach that it would be necessary to add their closed-source code to qemu which is not going to happen. You might have better luck with AMD card "passthrough" approach but I'm not sure if GPUs can be passed through qemu/kvm and if so, how the GPU-rendered image then gets displayed. So YMMV and don't expect much. There is a WIP effort for qemu though that is hardware vendor agnostic - it's based on creation of virtual GPU in qemu called Virgil that passes 3D drawing commands to GPU on host. The project is in initial stage though so it won't be ready even for testing for quite some time. FWIW, there has been discussion about it on spice-devel in recent days and it will be presented on upcoming KVM forum so you can get pretty clear picture about its status from these sources.
