[libvirt-users] TCP or TLS Connection error

Hi all i am using libvirt 1.2.0 with xen hypervisor 4.4.. I am facing error while remotely connecting other libvirt using TCP or TLS. I couldnt make libvirt to listen to the port.. I installed libvirt from source in debian. I enabled --listen option by uncommenting LIBVIRTD_ARGS="--listen" /opt/libvirt-1.2.1/daemon/libvirtd.sysconf .. I killed the current libvirt. and started the daemon again.. when i gave ps aux | grep libvirtd the listen is not enabled.. Pls guide me -- *Regards,Ajitha R*
