Thanks you guys. Fabian, I already look the capabilities of my Core2Duo, unfortunaletely it dont support VT.
At the time I'm using the second strategy: Using a Core2Duo as a Front-End and release all resources of the server to be use by cloud. I choose this option because it is more close to the proposal of official OpenNebula Documentation. I hope it works now! So I use one of my servers (With VT) as a Image Repository too. And now I have a little more question: With a NFS server configured. I have the Image Repository sharing its directory /var/lib/one. My doubt is: - Have I to insert the shared directory in the file /etc/fstab on all my nodes? So the node already have this directory avaiable when the machine starts. - Or Haven't I to do this? Does the directory only be mount when it is necessary? (sudo mount ...) And, if I edit the /etc/fstab, Do I have to do this in the node ImageRepository+Cluster at the same time? I hope not, because the directory is on the machine Thanks for the help.
