Also forgot to specify my VM external address is 10.7.7.105. The external
network CIDR is 10.7.0.0/16 gateway is 10.7.0.1.

Hi James,
Thanks for the response! Yeah Ive tried that no luck. My resolv.conf on a VM
(192.168.1.5) is as follows:
nameserver 192.168.1.3
nameserver 10.7.0.1
search openstacklocal
The first is the demo-subnet dhcp address.
The second is the outside network gateway/dns address.
Neither work. Whenever I try anything this what I get:
dig domain.com @8.8.8.8
; <<>> DiG 9.9.5-3-Ubuntu <<>> domain.com @8.8.8.8
;; global options: +cmd
;; connection timed out; no servers could be reached
Weirdly, when I try to do an nslookup from the VM and then tcpdump on port 53,
on the network node qrouter namespace I see no requests, but I do see requests
on the compute node:
15:37:36.150955 IP (tos 0x0, ttl 64, id 64629, offset 0, flags [none], proto
UDP (17), length 67)
192.168.1.5.35247 > 8.8.8.8.domain: 28059+ [1au] A? domain.com. (39)
15:37:41.151060 IP (tos 0x0, ttl 64, id 64630, offset 0, flags [none], proto
UDP (17), length 67)
192.168.1.5.35247 > 8.8.8.8.domain: 28059+ [1au] A? domain.com. (39)
15:37:46.151166 IP (tos 0x0, ttl 64, id 64631, offset 0, flags [none], proto
UDP (17), length 67)
192.168.1.5.35247 > 8.8.8.8.domain: 28059+ [1au] A? domain.com. (39)
Also I can do an nslookup from the namespace itself and works no problem:
ip netns exec qrouter-d9b5f02b-48c5-44a1-bc4b-7ba0336ee201 nslookup
www.google.com
Server: 10.7.0.1
Address: 10.7.0.1#53
Non-authoritative answer:

Address: 74.125.225.146
...etc....

Hi Amit,
Have you tried specifying a name server with dig? Ie. dig domain.com @8.8.8.8
<—google DNS
Have you confirmed your instances have a resolver configured in
/etc/resolv.conf? This usually occurs via DHCP.

Subject: [Openstack] Name Resolution problem (ICEHOUSE)
Hi all,
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:
No internet access from VM - Ask OpenStack: Q&A Site for OpenStack Users and
Developers

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 ...
