hi all:
I'm trying the migration of ploop from node1 to node2
the directory /vz/private of node1 is a local dirctory on node1.
the directory /vz/private of node2 is a nfs which I mounted from node3


I started the CT with ploop on node1
I migrated the CT as: vzmigrate -v --online -r no 192.168.5.159 1113

and I got the message as follow:

Starting online migration of CT 1113 to 192.168.5.159

Dose anyone know the problem? is it fixable or some wrong with my configuration?
BTW : is it possible to put the private of CT on the nfs?

Thanks!

Tommy
