You have been subscribed to a public bug:
After installing kernel package linux-image-
unsigned-5.14.2-051402-lowlatency from
https://kernel.ubuntu.com/~kernel-ppa/mainline/ starting libvirtd, and
thus qemu, results in 2 stack traces. Then libvirtd stops.
Rolling back to 5.11.0-34-lowlatency fixes the problem.
