Re: [lago-devel] [ovirt-system-tests] What is the correct value of the engine's answer file entry OVESETUP_CONFIG/fqdn ?

"localhost.localdomain" can work, for this usage, if you connect locally - with the browser running on the engine machine. Otherwise it will obviously not work (with normal settings - of course you can edit your local /etc/hosts to point this name at the engine machine, and potentially break other local services that expect this name to point to local machine). If you intend to ask if it's "valid", then it's a bit more complex. AFAICS, in engine-setup we never had 'localhost' hard-coded. There was code that prevents something more general if a certain env key was set (e.g. in an answer file), e.g. OVESETUP_CONFIG/fqdnNonLoopback=bool:True By default, it was set only if the all-in-one plugin was installed and configured (i.e. if you replied 'yes' to 'configure vdsm on this host?'). ( This was done for these bugs: https://bugzilla.redhat.com/show_bug.cgi?id=928667 https://bugzilla.redhat.com/show_bug.cgi?id=948311 You won't find references to them in current code's commit messages because it was rewritten for 3.3: https://gerrit.ovirt.org/14889 https://gerrit.ovirt.org/14699 ) In master (4.0), all-in-one is dropped. You can still set the key. In <=3.6 we still have all-in-one (announced deprecated). In ovirt-hosted-engine-setup we had a bug [1] asking to prevent that for the _engine_ fqdn. The code doing this was originally written inside that git repo, hardcoding 'localhost' [2]. Later it was moved to ovirt-setup-lib, and the code there was largely copied from engine-setup code (which was a bit more general), also going through a series of fixes - see [3][4][5] or just the current code. Currently, both engine-setup and ovirt-hosted-engine-setup call ovirt-setup-lib. So ovirt-hosted-engine-setup should prevent that for the engine fqdn in all (recent) versions. We also have other related issues, e.g. [6].
