[one-users] OpenNebula multi-site --- question

[Giovanni Ponti]

I'm Giovanni Ponti, an ENEA researcher based in Portici Research Center.
One of my research interest is Cloud Computing, and I'm following and 
organizing cloud experiences in ENEA-GRID.

We are planning to have a multi-site cloud envorinment among ENEA 
computational centers (that are six). At the moment, we have installed 
OpenNebula only in one site (i.e., Portici one), and we are evaluating a 
further installation on another ENEA site.

My question regards the ways in which two (or more) OpenNebula 
installation may communicate and/or interact to export a whole 
integrated cloud enviroment. In particular, as I know that OpenNebula 
provides several interfaces to export cloud facilities and to perform 
remote action (e.g., OCCI), it is not particularly clear how aspect 
ragardering virtual machines are handled, such as vm migration among 
sites or other.

Thanks in advance for your reply(s)

Giovanni
