I‘m very exited to hear that qemu has supported live migration without shared storage and I also have found some persons give their experiments, for example: （http://blog.allanglesit.com/2011/08/linux- kvm-management-live-migration-without-shared-storage/） # virsh migrate --live vmname qemu+ssh://kvmnode02.allanglesit.net/system --copy-storage-all --verbose --persistent --undefinesource I repeated the above experiment, but I failed. I want to know I need which version of qemu and libvirt and how the progress of the new feature.
