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!! ;) Il 17/12/2013 15:10 Steven Timm ha scritto: > OpenNebula Frontend in a VM It can be done, but how well it performs > depends on what data store you > are using.
