Hello again!
Trying to suspend + resume a VM had the same result.
However, I managed to fix this meanwhile.
It seemed that my system datastore was shared. After changing it's TM_MAD to
ssh from sunstone everything worked fine.
Hope it will help others too!

Hello!
I have installed Latest Series 4 Stable of OpenNebula.
I have 2 worker nodes and 1 front-end. On both the worker nodes I can deploy
virtual machines.
The problem occurs when I try to migrate one virtual machine from one of the
worker nodes to the other one. I am trying to create a cold migration and I am
not using a shared data storage, as I am counting on scp .
So, for example I try to do this operation: Migrate from host A to host B.
In my opinion, a POSSIBLE CAUSE might be the followin:
-the checkpoint is not copied to the host B => no such file or directory
Just to be sure, can you paste the output of onedatastore list? All the DS
should have 'ssh' as the TM (transfer manager).
Do you have the same problem if you try to suspend + resume a VM?

I would appreciate any help!
