[one-users] migration not working completly

[Ross Nordeen]

I have open nebula deployed with one head node and 2 compute nodes,  I have no problems live migrating from cn1 to cn2 but I get failures live/cold migrating from cn2 to cn1.  is there any reason I would not able to a) not save the state of any of my machines and why live-migration works one way but not the other??  Thanks

here is my vm.log file after a live-migration, migration, and than suspend:
