[one-users] OpenNebula 3.2 VM deployment failure

Hello,

VM_DIR is only used for nodes, OpenNebula always expect to have image
files for the VMs in /var/lib/one. You can do two things in you
frontend:

 * Mount you shared storage in /var/lib/one
 * Make /var/lib/one a symlink to /p00 (supposing that the shared
storage is accesible in this path from the frontend)

Before making any of these changes stop OpenNebula and move the files
/var/lib/one to the shared storage.

Cheers
