[ovirt-users] how to move from hosted-engine to standalone engine

One issue I have with hosted-engine is that when something goes wrong it has a domino effect because hosted-engine cannot communicate with its database. I have been thinking to host ovirt engine separately on a different hypervisor and have all my host undeployed. However for efficiency my networks are separated by their functions. So my questions are as follow 1) is it a good idea to host the engine on a separate kvm 2) what network does this engine need to access. Obviously ovirtmgmt, and display to access it but what about storage. Does it need access to itor can it access it through ovirtmgmt and the SPM? 3) Is there a recipe or howto available to follow Thanks Pascal
