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. > By the way, I installed my libvirt under directory working.

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)
