Comment 10 for bug 1409661

Hi. I work with Roger and we assumed you are subscribed to issues in launchpad when you make a comment, appears not so! Sorry for not replying earlier.

We don't have access to the internet from Fuel in our environment, nor any internal DNS servers. And the Fuel setup does not let you install Fuel without specifying a DNS server, so we kept the default, namely Google's 8.8.8.8.

This leads to DNS requests being sent to 8.8.8.8 on lookups, and they all fail by timing out.

    dockerctl shell cobbler

Check /etc/dnsmasq.upstream, we changed 8.8.8.8 to 127.0.0.1, making it give up instantly.

What I actually wanted to do was to disable DNS forwarding, but this solved the problem for us so we moved on to other issues. :)

  [root@acef1204c473 /]# host node-7
  node-7.domain.tld has address 10.20.0.5
  Host node-7.domain.tld not found: 5(REFUSED)
  Host node-7.domain.tld not found: 5(REFUSED)

Even if this obviously isn't ideal.

This fixed both the issue with it being slow to ssh to a node from Fuel using the node name (node-7) instead of the IP, and it also fixed the NOVNC issue.
