            <div bgcolor="#FFFFFF" text="#000000"> Hi,<br>
              <br>
              <br>
              I'm testing sheepdog 0.9 on two hosts.<br>
              <br>
              <br>
              I tried to do kvm live migration:<br>
              $ virsh migrate --live test-vm
              qemu+ssh://test-host2/system<br>
              <br>
              <br>
              but I get the following error:<br>
              error: internal error: process exited while connecting to
              monitor: qemu-system-x86_64: -drive
              file=sheepdog:test-vm-disk,if=none,id=drive-virtio-disk0,format=qcow2,cache=none:

              cannot get vdi info, VDI is already locked, test-vm-disk 0<br>
              qemu-system-x86_64: -drive
              file=sheepdog:test-vm-disk,if=none,id=drive-virtio-disk0,format=qcow2,cache=none:

              could not open disk image sheepdog:test-vm-disk: Could not
              open 'sheepdog:test-vm-disk': Input/output error<br>
              <br>
              <br>
              the VDI is locked by dog:<br>
              $ dog vdi lock list<br>
              VDI | owner node<br>
              test-vm-disk | IPv4 ip:test-host1 port:7000<br>
              <br>
              <br>
              if I remove the VDI lock the live migration works
              correctly:<br>
              $ dog vdi lock unlock test-vm-disk<br>
              <br>
              but after the live migration I can't relock the VDI.<br>
              <br>
              <br>
              VM disk definition:<br>
                  <disk type='network' device='disk'><br>
                    <driver name='qemu' type='qcow2'
              cache='none'/><br>
                    <source protocol='sheepdog'
              name='test-vm-disk'/><br>
                    <target dev='vda' bus='virtio'/><br>
                  </disk><br>
              <br>
              <br>
              How can I do the live migration safely with sheepdog 0.9?<br>
              <span lang="en"><span>Or what am I doing</span> <span>wrong?</span></span><br>
