I believe they're using Chrome OS and running into the issue discussed here: https://support.google.com/chromebook/thread/130336497/qemu-on-bullseye Apparently in this case libvirt is running inside a Debian-based LXC container, and the upgrade from buster (Debian 10) to bullseye (Debian 11) is what broke the virtualization functionality. Debian 10 had libvirt 5.0.0 - is it possible that the XATTR thing that's failing was introduced after that, and that's why the error wasn't showing up before? -- Andrea Bolognani / Red Hat / Virtualization
