To put it simply, it works well in SR-IOV mode. My issue is: when I pass through the entire GPU to a virtual machine (and it runs normally inside the VM), shutting down the VM sometimes causes the PVE host to freeze — this happens randomly.
For example, it might occur only once out of 10 VM shutdowns, or it could happen the first time I shut it down. On another occasion, no matter how many times I started and shut down the VM, I couldn’t reproduce the issue — but when I restarted PVE, the host froze during the shutdown phase.
I have a KVM device, so I can confirm it’s definitely a freeze — there’s no output at all, and no response whatsoever.
nothing special in dmesg and journal
Any suggestion?
