live migration of hosted engine between two hosts
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.

When adding the second host, whether to select the hostedengine deployment? On Wed, Aug 22, 2018 at 5:43 AM, Douglas Duckworth <dod2014@med.cornell.edu> wrote:

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.

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. On 22 August 2018 at 08:51, Simone Tiraboschi <stirabos@redhat.com> wrote:
