Hello guys.
I had a Proxmox server running fine for about a year with two VMs, one Windows and one MacOS, each with their own GPU (RTX 2080 Super and Vega 64 respectively).
For some dumb reason I decided to upgrade my server, and already in the process (after upgrading to 6.4) I started to have problems booting up the VMs.
The Windows VM (with the nVidia card) would just loop trying to start the VM, spawning a new PID every second and making it a nightmare to kill the VM.
The MacOS VM (with the AMD card) just plain threw an error in the lines "could not read tail".
Removing the VGAs from the list of passed devices made it possible to boot the VMs, but since they're my workstations, I kinda need them with the VGAs.
I tried to follow some GPU passthrough tutorials just in case the update managed to overwrite some VFIO-related stuff, but no help.
Then for some other dumb reason, I decided to pull the trigger and bought a community license and still try to upgrade to Proxmox 7.0 in the hopes it would fix itself.
Now it's even worse. Now it complains it can't start the VM with the following error:
Even though both SMV and IOMMU are obviously enabled (I checked it). I can't even boot an Ubuntu VM with no VFIO anymore!
I'm starting to lose any kind of hope of fixing it, but decided to try to get some help here before trying the drastic solution of formattingthe server, going back to 6.2 and having to reconfigure everything.
Any help is much, much appreciated!
