[libvirt-users] Cannot migrate vm between servers

Hello, I issue the command below to migrate virtual machine "jabber" from host vmserver5 to vmserver3 I see the machine is created at the destination, paused on both sides, but the process fails with the error below (and the destination VM is removed) root@vmserver5:~/# virsh migrate --p2p --unsafe jabber qemu+ssh://vmserver3/system error: internal error: migration was active, but no RAM info was set Relevant Software versions: vmserver5: ||/ Name Version Architecture Description +++-==============================================-============================-============================-= vmserver3: ||/ Name Version Architecture Description +++-==================================-=============================-============-============================ ii kvm 1:1.1.2+dfsg-6+deb7u8 amd64 dummy transitional package from kvm to qemu-kvm ii libvirt-bin 1.2.9-9~bpo70+1 amd64 programs for the libvirt library ii qemu-kvm 1.1.2+dfsg-6+deb7u8 amd64 Full virtualization on x86 hardware Both machines have shared storage mounted in same place. Very little info on web regarding this error. Can anyone suggest what is going on? Thanks in advance Chris Lewis
