Hi all,
I am very interested in setting up a virtualized infraestructura that provides HA to my Installed VMs. As read, OpenNebula does provide it but I have some technical questions Regarding its functioning: I would like to better understand the HA model behind the scenes on OpenNebula. I mean, In Citrix or vmware you have a manger node where you configure HA, but the real nodes Managing it are the physical hosts (hypervisors). This is great because it avoids a single Point of failure you can find in other packages where the manager node is responsible for Monitoring and managing HA capabilities. Also, you avoid to devoting duplicated resources to Maintain two management servers up and running in active/passive state. I have found this a shortcome for some configurations And would like to know the mechanisms under OpenNebula. I have read it uses a persistent Database so I understand it will be located on an external storage that can be replicated and so on, But I am not sure if I will need to run two instances of the management server in order to Have HA HA J. ¿Any clues on this? Thanks in advance, Jose.
