Thanks!

I am downgrading to an older kernel to see if kdump will work.  My other hypervisor works fine with 3.10.0-862.9.1.el7 but this host has a newer one.

Sorry for disorganized nature of this thread.

Can you tell me how to get ib0 set as migration network?

OK, after a while this host goes into bad state due to "HA score."  Could this be due to kdump not being enabled?
it's not kdump related.

The host will come back to a reasonable HA score by itself after about 10 minutes.

Thanks everyone!

During reinstall ran into this error:

I was then able to successfully re-install hypervisor after disabling kdump.

Migration now works!!!!

So both hosts have Infiniband.  How can I set that up as Migration network?  I would rather that ovirtmgmt not be the migration network since it's only 1Gb vs 56Gb FDR.

What used to catch me out here, is that you need to set 'Choose hosted engine deployment action' to deploy when adding a new physical host.

The hosts that are eligible for running the engine VM should be flagged with a silver crown, the host that runs the engine VM with a gold run.
In your screenshot I see the gold crow but not the silver one on the second host so you have to double check if hosted-engine stuff has been correctly deployed there.

Hi

I am trying to live migrate my hosted engine between two hosts.  

Both hosts are now up.

The hosted engine exists on shared NFS storage mounted on both hypervisors.

Though when I tried to migrate the VM I am told that's not possible.

Could this be since I never defined migration network?  If so I tried doing that in the oVirt UI as described https://ovirt.org/documentation/admin-guide/chap-Logical_Networks/ though many of these options have changed.
