Did you check your configuration before attempting the migration?

Hi all:
I upgrade Openstack to Icehouse and find that there is a new horizon
feature in which VM can be live migrated. So I tried to move a VM from
node2 to node1, but got a "*Error: *Failed to live migrate instance to
host "node1.expr-zone"." error.
There seems no error logs in nova compute services of node1 or node2,
the nova api and nova schduler on controller does not give any hints
either. The only error is found in apache error log:
