'libvirtd' was separated into specific sub-daemons for specific object
or hypervisor:

 - hypervisor drivers:
   - virtqemud - for managing qemu machines
   - virtlxcd - for lxc
   - ... for all other hypervisor drivers...
 - network driver
    - virtnetworkd
 - storage driver
    - virtstoraged
 - secret driver
    - virtsecretd

etc...

If you are running modular daemons you then don't use 'libvirtd' at all,
but rather the client library communicates with the appropriate daemon
based on the object type.
