[one-users] Front-End node

[Giancarlo De Filippis]

Thanks very much for "rapid" answer. 

Is possible to have a doc for installation of front-end as VM in one
host (already in one cluster???) 

And.... can onenebula manage yourself (manage the vm installed in node)?


We have a shared filesystem with glusterfs 

... sorry for my english!! ;)
