Ok after some playing around, it looks like a trouble with Quadro cards. If I use now with ovit 3.6.7 tesla 2050 everything works as expected! nice. *********************************************************** Dr. Arman Khalatyan eScience -SuperComputing Leibniz-Institut für Astrophysik Potsdam (AIP) An der Sternwarte 16, 14482 Potsdam, Germany *********************************************************** On Wed, Jun 15, 2016 at 11:57 AM, Martin Polednik <mpolednik@redhat.com> wrote:

Hi, I am looking for some solution with multiple GPUs(FX5600quadro and TESLA2050) The drivers are not compatible in the bare metal, Therefore I was trying to use passthrough as described here:
http://www.ovirt.org/develop/release-management/features/engine/hostdev-pass...
After installing the nvidia driver on the guest everything looks nice. After running 2 or 3 times nvidia-smi to see the GPU status, the device disappear. I just tested with both gpus, with different drivers from nvidia, same situation.
My environment is host and guest-Centos7.2, ovirt 3.6.6 engine(but host has 3.6.7RC due to the fix in passthrough gui)
Are there successful stories with GPU+Ovirt?
Actually the cards you are using should work pretty well. If I understand correctly, the device disappears from the guest? That would most likely be problem in NVIDIA's smi tool or drivers. Still, supplying VDSM logs (from start to VM's destruction) from the host could help us debug the issue.
Thanks,
Arman.
