Doing quantum subnet-update sub1 --dns_nameservers 8.8.4.4 8.8.8.8 works. BTW from horizon you can pass one dns also. Thanks guys Paras. On Fri, May 17, 2013 at 3:47 PM, Darragh O'Reilly < dara2002-openst...@yahoo.com> wrote: > Hi, > > I reckon this is because dnsmasq is isolated in the dhcp na

Hi, I reckon this is because dnsmasq is isolated in the dhcp namespace. You can use  DHCP to push out a specific nameserver: $ quantum subnet-update sub1 --dns_nameservers 8.8.4.4 8.8.8.8 I can't seem to figure out the syntax to pass just one (list=false is not  working). Or you could use Horizo

Can you telnet to port 53 of local DNS ip from your instance (IP in your resolv.conf) ? If its not working then you might need to check your local quantum dnsmasq settings. On Sat, May 18, 2013 at 1:45 AM, Paras pradhan wrote: > Thanks. Yes I got the concept but something is not working. I can'

Thanks. Yes I got the concept but something is not working. I can't resolv the hosts from my instances. Thanks Paras. On Fri, May 17, 2013 at 3:10 PM, Ashok Kumaran wrote: > It will not populate the external DNS ip in your resolv.conf . Instead > the external DNS will be used by the local quan

It will not populate the external DNS ip in your resolv.conf . Instead the external DNS will be used by the local quantum dnsmasq for the name resolution purpose. For an instance lets say that your network node has a DNS ip of some xx.xx.xx.xx in its resolv.conf . By adding the same IP to the dh

So adding dnsmasq_dns_server= "external DNS IP" should populate the resolv.conf of my instances with the externel DNS IP? I did that but still seeing the same ip on resolv.conf. Paras. On Fri, May 17, 2013 at 2:17 PM, Ashok Kumaran wrote: > I am assuming that you have a DNS externally and you

I am assuming that you have a DNS externally and you want the instances to use that DNS. If this is the requirement then you will have to add dnsmasq_dns_server= "external DNS IP" in your /etc/quantum/dhcp_agent.ini.Now your launched instances(VM's) can use external DNS through quantum dnsmasq. Pl
