I believe when it occurred when the running the engine-setup.

Yep. I tested things to make sure it could resolve before I started the 'hosted-engine --deploy'.

I did answer "Yes".

That is my take as well.

Scratching my head as I config'ed dnsmasq to provide local dns and to read from /etc/hosts for hosted-engine-1.pcstrac.com.

The only thing I think I flubbed was neglecting to add the host's IP to the host's /etc/resolv.conf.

Scrubbing and staring again.
