If running libvirtd via systemd, it gets a 64 MB memlock limit, but if running from the shell it will only get 64 KB on a Fedora 33 system. The latter low limit causes any attempt to use BPF to fail and it is not obvious why.
This improves the error message thus:
# virsh -c lxc:/// start sh error: Failed to start domain 'sh' error: internal error: guest failed to start: Failure in libvirt_lxc startup: failed to initialize device BPF map; locked memory limit for libvirtd probably needs to be raised: Operation not permitted
