I’m trying to set up OpenNebula from scratch, and I’m having a tough time understanding the Best Practice design/architecture when it comes to the Front End hosts. I have throughly reviewed all documentation. I desire to have the Front End hosts be HA, so my plans were to follow the HA documentation.
What I’m not understanding is where should those Front End hosts live?? We have very large hardware here, so it doesn’t make sense to waste resources and instal the Front End stuff on bare metal… so I was planning on setting them up as VMs.
It seems like if you want to go that route, you have to already have another VM infrastructure set up, outside of OpenNebula, in order to get started. Is that correct?
I was thinking that I could have an HA cluster of Front End VMs live on the actual OpenNebula hosts/cluster itself… but it seems you can’t necessarily do that because you have a chicken and egg situation.
What is the recommended architecture in this situation?
