Hi, I am trying to configure ovirt(ver 3.5). The fqdn I provide during the step "Host fully qualified DNS name of this server” is reverse resolvable. I am able to verify that with nslookup of the IP address.
But, I keep getting the following error: Host fully qualified DNS name of this server [localhost.localdomain]: xyz.xyz.xyz.com [ ERROR ] Host name is not valid: The following addresses: 10.xx.xx.xx did not reverseresolve into xyz.xyz.xyz.com
( BTW, there is a bug here - missing space between 'reverse' and 'resolve'. Now pushed [1] for this to master branch. [1] http://gerrit.ovirt.org/37424 )
How is ovirt-engine trying to reverse lookup the domain? If I know that, I could probably fix the issue.
You can see the code doing this check in /usr/share/ovirt-engine/setup/ovirt_engine_setup/hostname.py You can check the log, mentioned by engine-setup, in /var/log/ovirt-engine/setup, to try and see what failed. Generally, by default, the check above is ran only when configuring all-in-one. It looks up the input fqdn, and for each result address, looks up its reverse mapping (the PTR record) using 'dig -x', and checks that the result is equal to the input fqdn. Best, -- Didi
