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

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.

When adding the second host, whether to select the hostedengine deployment?

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.
