Few days ago libvirt has started to behave erratically on my laptop. It consumes a high amount of CPU without any apparent reason. ALL my VMs are shutoff, why is libvirt using up to 100% CPU if no VMs are running?
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
203328 root 20 0 1640992 37056 22308 R 86,1 0,1 22:57.03 libvirtd
Killing the process makes my laptop happy. Problem comes back as soon as the process is started again. No idea how to debug or fix this, any help is welcome.
Using up to date Ubuntu 21.10, kernel 5.13.0-30-generic.
