Hi all, I've a SUPERMICRO server with a M10 GPU (at the moment i've a free-trial license) and i'm using oVirt 4.4.2. My issue is very strange and it seems to be a bug because i can reproduce it: 1. Create a VM (i've tested on Win10Pro/WinServer2012R2) with a vGPU and install the driver (without driver installed, this issue does not appear); 2. Restart the VM. At this point the physical server restarts. Instead, when i shutdown the windows vm, this issue is not appear. I've also tried with a centos 8 vm and it works very well (no reboot). All NVIDIA driver's are update at the 2020-09-30 latest release (11.0). All windows driver are installed (virtio-win-0.1.189). The VM works very well and the vGPU too. This is my very first test with vGPU and i can't understand the reason of this issue. NVIDIA enterprise support told me that it's an ovirt problem, because Windows guest operating system are supported only under Red Hat subscription programs. Has anyone else had the same problem or can you help me? Thank you in advance
