[one-users] can't create VM with shared vm dir

[Shantanu Pavgi]

Hi, 

Figured out from Tino's  reply earlier: http://lists.opennebula.org/pipermail/users-opennebula.org/2011-March/004240.html 

It's working now. Mounted NFS hosted var directory under $ONE_LOCATION/var on OpenNebula server and under VM_DIR location on client side.

The VM dir (/groups/one-vm-dir) contains only deployment.0 file and disk.0 is not created here. The VMM is failing to create a VM as there is no disk image in the VM_DIR.
