I don’t have a diagram, but the answer to your question is yes.

There is some good information in the admin guide about the role that the engine takes to fence the compute host:

Subject: [External] : [ovirt-users] fencing state/sequence diagrams

 

Hello everyone,

After a network outage, we experienced a situation of chaotic connectivity between the oVirt manager (located on a VM outside the cluster) and the hypervisors themselves.

During the incident, while only the connectivity between the manager and the hypervisors was difficult, during the recovery we had fencing of several of our hypervisors.

I'm looking for a diagram or text that describes all the rules for triggering fencing.

Specifically, I have questions about the following (just in case):
* Does the manager play an active role in the decision to fence a hypervisor?

Regards,
Renaud
