RH does have firewall rules you may want to see if DNS is going out. I know you said that it goes outside but you can also check the order if in nsswitch.conf etc..
Have a good day, ciao -- Remo Mattei November 12, 2013 at 14:32:52, Xin Zhao (xz...@bnl.gov) ha scritto: 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?
