Libvirtd loads all the configs under /etc/libvirt into memory, so if
you delete them, libvirtd will still know about them until you restart
it.

If you are runing libvirtd as non-root then it uses $HOME/.libvirt

If you built a custom libvirtd from source and run it as root, then
it'll use $sysconfdir/libvirt  (where $sysconfdir is the --sysconfdir
value passed to the configure script)
