OpenNebula

I'm trying out opennebula-3.0.0 with the vmware-3.0.0 driver, and ESXi 4.1
it's mostly working well, but I have a problem with persistent images.

Starting a persistent vm works well, shutdown also works (the first time),
but the problem is that it tries to save the directory /src/clod/one/var/<vm>/disk.0 back to the image repository on shutdown,
and those files causes the save to fail the next time anyone instantiate and shutdown again on that image.

I have looked at /srv/cloud/one/var/remotes/image/fs/mv that is called when shutting down
and it seems to me that the script does not detect that the image
is symlinked because it's looking at the directory instead of the symlinked files.
(as in vmware-2.98 which could not even start a persistent image because of how ESXi treats linked directories).

I changed this part.
