Can you please compare versions of all installed packages between the source
and destination machines?

I assume the failure above is right after engine-setup, right? Before continuing
the interaction on hosted-engine side?

Did you try to restart the engine (systemctl restart ovirt-engine)? Did it fail
the same way?

How much memory do you have on the source machine? And how much does the engine
actually use there?

How large is your system (hosts, VMs etc)?

Best,
