[fedora-virt] Sanlock + libvirt

Hello, in sanlock docs (https://fedorahosted.org/sanlock/) there is described, how to use it. There is no mention about NFS. Can I use sanlock with LVM (without NFS) with livbirt? It this feature implemented in libvirt for Fedora or RHEL? For libvirt I need to define lease dir as: disk_lease_dir = "/var/lib/libvirt/sanlock" but this have to be a directory. How to configure it to use sanlock on LVM? SAL
