If you see this Nov 14 17:18:17 logs.go:41] skydns: failure to forward request "read udp nodeIP:50958->nodeIO:53: i/o timeout"
systemctl restart origin-node.service
journalctl -f -u origin-node.service |grep "skydns: failure to forward request"

RHEL 6.3 veewee templates for vagrant use

These templates can be used to feed to veewee to spin up an el6 basebox for use with vagrant.

There are some coded values in definition.rb and ks.cfg which point at Yale-ishness. Amend to point at local RHEL iso/yum repo.

Built successfully with veewee 0.2.3, vagrant 1.0.3, Virtualbox 4.1.18.
