[libvirt] Probs connecting QEMU hypervisor with URL ?

Hi, i tried to use virt-viewer to connect to a remote machine running libvirt & kvm-qemu at FC9 - but it failed. So, I run virsh without the URL directly on FC9, it works (e.g. virsh list). If I use a connection URL, it failed. Did I miss something ? regards Danny [root@xxx03 ~]# virsh list Id Name State ---------------------------------- oot@xxx03 ~]# virsh -c qemu+tls://localhost list libvir: Remote error : Certificate's owner does not match the hostname (localhost) libvir: Remote error : unable to connect to 'localhost': Invalid argument error: failed to connect to the hypervisor [root@xxx03 ~]# virsh -c qemu+tls://xxx03.domainname.com list libvir: error : could not connect to qemu:// error: failed to connect to the hypervisor *** Port is available: [root@ xxx03 ~]# netstat -nl | grep 16514 tcp 0 0 0.0.0.0:16514 0.0.0.0:* LISTEN *** Also, a ssh does not work: [root@xxx03 ~]# virsh -c qemu+ssh://xxx03.domainname.com list root(a)xxx03.domainname.com password: libvir: error : could not connect to qemu:// error: failed to connect to the hypervisor ** Connecting directly works: [root@ xxx03 ~]# virsh -c qemu:///system list Id Name State ---------------------------------- ** but not with the remote name like [root@ xxx03 ~]# virsh -c qemu://xxx03.domainname.com /system list libvir: error : could not connect to qemu://xxx03.domainname.com /system error: failed to connect to the hypervisor
