Re: [vfio-users] VFIO and random host crashes

I'm not convinced the ones I've seen are power related, my system has been running videos in a loop for days, completed a few folding @home jobs, done some compiling, and I even added another (idle, low power) video card since the last hang. Storage doesn't jive with my observations either. I'm

Re: [vfio-users] VFIO and random host crashes

Are you using isolcpus or nohz_full? I've seen similar lockups (even the reset button not working) running a slim host with a Win8/NVIDIA VM + Fedora/IGD VM tuned to try to give the host the minimal resources possible, but with the VMs overlapping CPUs because I only have a quad-core. I built a

Skimming... Most of those AMD CPUs in the amd.com link do not support AMD-Vi User-level access to devices... No, don't do this. System mode libvirt manages device permissions. If you want unprivileged, session mode libvirt you need a whole other wiki page. Binding to VFIO... Gosh I wish those
