[libvirt-users] create ovs port without root

Hello! How can i operate with openvswitch without root rights? For example - i can add my user to kvm group and create vm from libvirt with my own user, but now i'm failed with creating port. errors in logs: Mar 06 14:04:46 selfip.ru ovs-vsctl[19065]: ovs|00001|vsctl|INFO|Called as ovs-vsctl --timeout=5 -- --if-exists del-port Mar 06 14:04:46 selfip.ru ovs-vsctl[19065]: ovs|00002|vsctl|ERR|'del-port' command requires at least 1 arguments Mar 06 14:04:46 selfip.ru libvirtd[6418]: internal error: Child process (ovs-vsctl --timeout=5 -- --if-exists del-port) unexpected exit status 1: ovs-vsctl: 'del-port' command requires at least 1 arguments Mar 06 14:04:46 selfip.ru libvirtd[6418]: Unable to delete port (null) from OVS: Operation not permitted -- Vasiliy Tolstov, e-mail: v.tolstov(a)selfip.ru jabber: vase(a)selfip.ru
