I tried the command locally on the libvirtd host "virsh -c lxc:/// domjobinfo", I got an error "error: this function is not supported by the connection driver: virDomainGetJobInfo"

virDomainGetJobInfo is for getting information about background jobs
(such as save/restore/migrate), it has nothing todo with CPU usage.

For CPU usage you need virDomainGetCPUStats
