Hi,<br>
I am looking for some solution with multiple GPUs(FX5600quadro and<br>
TESLA2050)<br>
The drivers are not compatible in the bare metal, Therefore I was trying to<br>
use passthrough as described here:<br>
<a href="http://www.ovirt.org/develop/release-management/features/engine/hostdev-passthrough/" rel="noreferrer" target="_blank">http://www.ovirt.org/develop/release-management/features/engine/hostdev-passthrough/</a><br>
<br>
After installing the nvidia driver on the guest everything looks nice.<br>
After running 2 or 3 times nvidia-smi to see the GPU status, the device<br>
disappear.<br>
I just tested with both gpus, with different drivers from nvidia, same<br>
situation.<br>
<br>
My environment is host and guest-Centos7.2, ovirt 3.6.6 engine(but host has<br>
3.6.7RC due to the fix in passthrough gui)<br>
<br>
Are there successful stories with GPU+Ovirt?<br>

Actually the cards you are using should work pretty well. If I<br>
understand correctly, the device disappears from the guest? That would<br>
most likely be problem in NVIDIA's smi tool or drivers. Still,<br>
supplying VDSM logs (from start to VM's destruction) from the host<br>
could help us debug the issue.<span class=""><br>
