Same problem with 4.4.8 async 1.

I'm deploying/restoring from novirt2 and the other host (still in 4.3.10) is novirt1.

I arrive at

[ INFO  ] TASK [ovirt.ovirt.hosted_engine_setup : Check actual cluster location]
[ INFO  ] skipping: [localhost]
[ INFO  ] TASK [ovirt.ovirt.hosted_engine_setup : Enable GlusterFS at cluster level]

[ INFO  ] TASK [ovirt.ovirt.hosted_engine_setup : Pause execution until /tmp/ansible.5f702qq5_he_setup_lock is removed, delete it once ready to proceed]

But then I'm able to connect to local engine web admin UI and novirt1 results up while novirt2 not responsive.

Every 3 seconds iinside engine.log I see these 3 lines

Can anyone telling what I can check?

Did you test SHE upgrade from 4.3.10 to 4.4.8 in your check flows?

BTW: I'm not using DNS but entries in /etc/hosts

Thanks,
