Ok, I had no CPU resrouces left this is why I could not deploy antoher 
to the MASTER, I have identified and resolved all of these issues. One 
questiosn about the concept of Clusters. If I remove the created Cluster 
under Infrastructure --> Clusters in SunStone will this effect anything 
else? Is it just a tag/grouping mechanism. I ask because when I hit 
'delete' in SunStone it says "This will delete the selected VMs from the 
database". That of course scares me but I think its wrong.

Now I am back to where I started, I am unable to migrate.

Some questions, this command what machine does it run on? The machine 
that it is on, or the machine it is migrating to? (So in my case Master 
being the machien the VM is on, and HOST being the machine we are 
migrating to).

As explained in my other emails, I can startup a new host without issues 
so its just this checkpoint/restore process that breaks.

I can run the command manually as root and the oneadmin user on the HOST.

So where do I look? What is my problem?

Thanks
