Didi,
Both source and destination machines (assuming you are referring to the
physical host source and virtual host destination of the migration) are
running ovirt-engine 3.5.2.1-1. However, the "source" is on CentOS 6.6,
whereas the "destination" is on CentOS 7.1. The source is running
postgresql(/-server) 8.4.20, Java 1.7.0_79, httpd 2.2.15. Destination is
running postgresql(/-server) 9.2.10, Java 1.7.0.79, jboss-httpd 2.4.6. I'm
not sure which over package version is relevant.
The failure occurs after engine-setup, and the web UI doesn't load, and the
host reports the engine is not up (I'm not in front of the host, so I don't
have the exact language).
Our current setup has 2 physical hosts, ~15 active VMs. Each host has 64GB
RAM. Even with all the VM on one host, the utilization is less than 50%. We
have another physical storage server, that provides the NFS storage backend
to the hosts and VMs. Prior to attempting the hosted-engine migration, I
migrated all the VMs to host #1, where the engine was originally installed.
I then removed host #2 from the host list via the UI, and performed
hosted-engine --deploy on host #2. A few other quirks I encountered:
1. I originally wanted to do "hosted-engine --deploy" on host #1, but that
it was unsuccessful due to it complaining the storage connection was busy
(or something).
2. I then tried to do "hosted-engine --deploy" on host #2, using the same
storage connection path as what I used for host #1 originally. The setup
process asked if it was an "additional host", I said no, but later it
cannot activate the storage connection.
3. Lastly I did "hosted-engine --deploy" on host #2, but pointing to a
different storage connection path, still on the same storage server. This
was successful until the I encountered the failure in question.
Thanks,
Haven

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,
