Hi,

I have resolved this in such way.

On the engine host connect to db:
su postgres
psql -s engine

Then delete host from db manualy:
select vds_id from vds_static where host_name = 'HOST_NAME';
delete from vds_statistics where vds_id = 'id';
delete from vds_dynamic where vds_id = 'id';
delete from vds_static where vds_id = 'id';

A log will be nice.
However, can you please compare /etc/vdsm/vdsm.id in both hosts?
If not available at new host it might be a bios issue, try to uuidgen > /etc/vdsm/vdsm.id and add host.
