Hello.
I have a host with an NVIDIA RTX 3090. I configured PCI passthrough and it works fine. We are using it for CUA and Matlab on Ubuntu 20.04.
The problem comes sometimes on rebooting the virtual machine. It doesn't happen 100% of the times but eventually after 3 or 4 reboots the PCI device stops working. The only solution is to reboot the host.
While reviewing the system I noticed that, though I had run dist-upgrade, the host didn't had the latest kernel. Upgrading from kernel 5.8 fixed the problem. So it seems it was a vfio problem as Erik pointed. Thanks !
