[ovirt-users] Error while executing action: Cannot add Host. Host with the same UUID already exists.

[Alon Bar-Lev]

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.
