Hi, i installed Engine 3.0 and  Node Ovirt 2.6, but it seems very unestable. Sometimes machines doesnt starts, nodes doesnt vinculate or UI doesnt work fine. I have only 2 nodes and storage its on the same physical machine than engine.

-¿Does Node Ovirt 3.4 work with Engine 3.0?
-¿Its necessary shutdown Nodes to do engine upgrade?
-¿Are there any problem having the same physical machine for engine and storage? ¿what are advantages have on diferents machines?

Thank you
