A coworker and I are trying to bring up some nvidia vGPU VMs on ovirt 4.3, but are experiencing issues with the remote consoles for both Windows and Linux.

A windows10 VM for example works OK with a windows remote desktop client after enabling the service inside the VM, but using the oVirt VM portal spice/vnc seems to cause the mouse pointer to disappear and clicks seem to go nowhere.

We're more likely to want linux VMs though.

CentOS not booting all the way to gnome desktop after installing the nvidia driver.

What works well for you? 

Are there known tweaks I should try to make?

Any helpful hints?

Thanks!
