<div class="moz-cite-prefix">Thanks for all the reply, as Paul said,
the dnsmasq version doesn't appear to be the issue here. <br>
<br>
I also tested dns between 2 different VM subnets, instances can
ping each other across subnets, they can also reach dns server of
the other subnet. But hostname can't be resolved across subnets. <br>
Although I am not sure if this is the same issue as it is for the
outgoing nameserver, or a feature by design ... <br>
<br>
Thanks,<br>

Hi Terry,<br>
<br>
I upgrade to version 2013.1.4 on all 3 hosts
(controller/network/compute). Unfortunately that doesn't
solve the DNS issue for instances.<br>
<br>
In the dhcp-agent.log, there is a message of:<br>
<br>
WARNING [quantum.agent.linux.dhcp] FAILED VERSION
REQUIREMENT FOR DNSMASQ. DHCP AGENT MAY NOT RUN CORRECTLY!
Please ensure that its version is 2.59 or above!<br>
<br>
Not sure if it's critical or not ...<br>
<br>
Thanks,<br>
Xin

Hello,<br>
<br>
I have a multi-host grizzly RHEL6 install, using
OVS. From the instance,<br>
I can ping external ips, but DNS resolv doesn't
work, it only works for<br>
other instances on the VM network.<br>
If I do subnet-update to add public DNS server ips
to the vm network,<br>
DNS resolv works for external hosts, but stops
working for other<br>
instances on the same VM network.<br>
Do I miss some configuration here?<br>
<br>
Thanks,<br>
Xin<br>

Which version of quantum are you using? In version
2013.1.4, a bug was fixed for adding a default route
in the namespace in which the dnsmasq agent runs so
that external DNS requests could be handled. See: <a
