Dear Stephane ,
Yes , both source and target nodes are connected to MAAS
From both source and target nodes maas connection removed through
lxc profile edit default
Please let me know anything else to be done with maas configuration settings .
Also i tried to make a copy of container with in same node
But , with my case bugzilla container while copying gets following error:
~# lxc copy bugzilla bugzilla1
Error: Create LXC container: IP address is already in use.
Tried with the same node where bugzilla lies ,we have partkeepr container make copy within container
And one more point is only biometric and bugzilla having the problem , rest all containers i can able to move to another node .
