[ovirt-users] oVirt on a single server

[Christophe TREFOIS]

Personally my use case is that I have 4 machines with different specs and storage sizing. So I setup four DC with 1 host each. Then I have hosted engine on one of the hosts. Storage is local shared via NFS so that I can move VMs around.

At this point we are not interested necessarily in HA.

Maybe for you that's the definition of a Dev environment as production has other attributes than just the type of storage?

Would be nice to hear your thoughts about this.

Kind regards,
Christophe
