Occasionally in the agent logs I see: sudo: unable to resolve host r-410-VM
When virtual router commands are run. I decided to dig into it today, and added "127.0.0.1 r-410-VM" to the /etc/hosts file on the router. WOW, what a difference, most of the router commands are far faster now. Adding IPs for example is pretty much instant, rather than 15-20 seconds. I'll push a change to /etc/init.d/cloud-early-config if nobody objects.
