Thanks for all the reply, as Paul said, the dnsmasq version doesn't
appear to be the issue here.
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.
Although I am not sure if this is the same issue as it is for the
outgoing nameserver, or a feature by design ...
Thanks,
Xin

Hi Terry,
I upgrade to version 2013.1.4 on all 3 hosts
(controller/network/compute). Unfortunately that doesn't solve the
DNS issue for instances.
In the dhcp-agent.log, there is a message of:
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!
Not sure if it's critical or not ...
Thanks,
Xin

Hello,
I have a multi-host grizzly RHEL6 install, using OVS. From
the instance,
I can ping external ips, but DNS resolv doesn't work, it
only works for
other instances on the VM network.
If I do subnet-update to add public DNS server ips to the
vm network,
DNS resolv works for external hosts, but stops working for
other
instances on the same VM network.
Do I miss some configuration here?
Thanks,
Xin
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:
https://bugs.launchpad.net/neutron/+bug/1181378 for more details.
