<DIV><SPAN style="FONT-WEIGHT: bold">I was trying to migrate one instance
from the compute node compute2 to another node compute1, but failed, the
nova-compute.log said compute2 failed to connect the 16509 port on
compute1, i noticed that the 16509 port is not opened on compute1, is there any
additional configuration for Live-Migration ? Which service listens on port
16509 ?</SPAN></DIV>
