Hi all
I am in the process of migrating a RHV 4.3 setup to RHV 4.4 and struggling with
the setup. I am installing on RHEL 8.3, using settings backed up from the RHV
4.3 install (via 'hosted-engine --deploy --restore-from-file=backup.bck').
The install process always fails at the same point for me at the moment, and I
can't figure out how to get past it. As far as install progress goes, the local
hosted-engine comes up and runs on the node. I have been able to grep for
local_vm_ip in the logs, and can SSH into it with the password I set during the
setup phase.
However the install playbooks always fail with:
2021-01-18 18:38:00,086-0500 ERROR otopi.plugins.gr_he_common.core.misc
misc._terminate:167 Hosted Engine deployment failed: please check the logs for
the issue, fix accordingly or re-deploy from scratch.
Earlier in the logs, I note the following:
2021-01-18 18:34:51,258-0500 ERROR
otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:109
fatal: [localhost]: FAILED! => {"changed": false, "msg": "Host is not up,
please check logs, perhaps also on the engine machine"}

connect to the host via ssh: ssh: connect to host rhvm.example.org port 22: No
route to host", "skip_reason": "Host localhost is unreachable", "unreachable":
true}
I find the unreachable message a bit odd, as at this stage all that has
happened is that the local hosted-engine has been brought up to be configured,
and so it is running on virbr0, not on my actual network. As a result, that DNS
address will never resolve, and the IP it resolves to won't be up. I gave the
installation script permission to modify the local /etc/hosts but this hasn't
improved things.
I presume I'm missing something in the install process, or earlier on in the
logs, but I've been scanning for errors and possible clues to no avail.
Any and all help greatly appreciated!
