Understood. For my use case, I need a robust way to reboot/stop the VMs, regardless graceful or not. Having to reboot the host won’t work for me (even if I can script it to automate detection and reboot).
In the mean time, I am still tweaking my LXC passthrough set up. This approach is far less involving (and easier) but it’s only my interim workaround solution.
I am praying someone from AMD will release something so that we can patch it (just like all other GPUs of theirs).
BTW, a friendly reminder to install the latest 3.04 bios to address the uefi exploit.
