Ha, I know I have. Not a problem, we're on #rdo if anything else comes up.

Take care

iptables (like I've told it to) and it was too restrictive.  I flushed
iptables, and disabled puppet (so it wouldnt turn it back on again)
rebooted the undercloud vm, and guess what?  It's on the network now.

setting $VIRTHOST to localhost, or the local IP of the box (192.168.3.10),
I've tried it both ways, which doesn't seem to make a difference.  I'm
running quickstart as my local use, not the stack user.
