[one-users] Stopping a VM erases it

[Sergi]

Hello,

we are using OpenNebula 4.6.2 under CentOS 6.5.

We have 2 hosts, one of these has also Sunstone and exports shared
datastores (system, image and file), named 'localhost'.
We also have another system datastore using the ssh driver.

We have an issue with stopping VMs ... from sunstone gui, powering off a
VM on the ssh system datastore and starting it again works; but stopping
(option on menu that includes undeploy and undeploy hard) deletes the VM
files and when trying to start it again, kvm cannot find the files (i.e.
checkpoint).
