[ovirt-users] Single server hosted engine... almost there

[Derek Atkins]

Hi Mark,

The error is correct, hosted-engine-1.pcstrac.com is not a valid hostname:

$ host hosted-engine-1.pcstrac.com
$

I'm lost, tho -- was this an error that occurred on the host during
hosted-engine --deploy, or was it an error that occurred in the hosted
enging VM when running engine-setup?

If the former, you need to ensure that you have a real DNS name for your
ovirt engine.  It's unclear (to me) that using /etc/hosts is sufficient.
However looking at the logs, it looks like it can locally resolve (to
xx.yy.18.122).

You might need to answer "Yes" to the /etc/hosts question..

The log seems to get far enough along that it presents you the engine vm
console URL?  It looks like the issue is that the engine vm cannot resolve
its own name.
