[libvirt] migration fails

Hello, I tried to migrate a kvm domain to a second identical machine with the command: virsh migrate --live dom1 qemu+ssh://second.machine.org/system which leads me to an unresponsive virsh on the second machine - 'virsh list' just takes forever and qemu wasn't started (the domain was not migrated), finally I have to kill libvirtd on the second machine. Because I'm new to libvirt I searched the web to find a solution for this behavior but without success. Please can someone on the list point me to the right direction how I can use libvirt to migrate kvm domains? I use kernel 2.6.29.1 and kvm-85 with libvirt 0.6.2 on an debian unstable system. Attached are debug logs generated by the source- and destination-machine. Thank you very much Jens
