Hi Tobias,

thanks for reporting the issue. You're right it should get the SIZE of the
origin image and not the default size.

I have patched it to do what you said. To deploy it, simply replace the
lvm/clone script with this one, and then do onehost sync.
https://github.com/OpenNebula/one/blob/master/src/tm_mad/lvm/clone

please let me know if it isn't working as expeceted.

thanks!

Jaime
