So I have a DNS (or at least it seems to be only DNS) problem with the VM's I have created. I cannot resolve anything from within the VM's. I can ping outside by IP (ie, I can ping google,etc but only by IP) but cannot do a dig, curl, nslookup, etc by name.
I have no clue why this is happening and Ive tried some of the solutions other have recommended at Ask Openstack but to no avail. I was hoping someone here maybe able to point me in the right direction. I have also posted the question at Ask, all the node
stack details are here:</div>

Hi all, So I cant seem to access the internet from my VMs. I can access the floating IPs from anywhere in our network and from all nodes now (controller/network/compute) just fine (but strangely I cannot access the private ips, the tenant network from any of
the nodes?!) but cant ...</div>
