Hi Carl,
I think there is another thread here related to the migration to another
network.
As far as I know, the check liveliness try's to access the ovirt's health page.
Does the new engine's ip has A/PTR record setup?
Also, check the engine logs, once the HostedEngine VM is up and running.
Best Regards,
