Can't full access to internet from instance , maybe problem dns !

[rubber-ant]

So do you suggest to upgrade all nodes ubuntu with : deb http://archive.gplhost.com/debian grizzly main deb http://archive.gplhost.com/debian grizzly-backports main

at the moment I have

openvswitch-switch | 1.4.0-1ubuntu1.5 | http://gb.archive.ubuntu.com/ubuntu/ precise-updates/universe amd64 Packages openvswitch-switch | 1.4.0-1ubuntu1 | http://gb.archive.ubuntu.com/ubuntu/ precise/universe amd64 Packages openvswitch | 1.4.0-1ubuntu1 | http://gb.archive.ubuntu.com/ubuntu/ precise/universe Sources openvswitch | 1.4.0-1ubuntu1.5 | http://gb.archive.ubuntu.com/ubuntu/ precise-updates/universe Sources

I have 2 compute / 1 net / 1 cont:

I can ping vm each other, I can ssh from outside , inside the vm I can ping google and bbc but I can't do apt-get update from example a vm with ubuntu cloud image or not able to surf from a vm instace with ubuntu desktop . so I think is a problem with DNs .

I have notice that : all cat /var/log/quantum/openvswitch-agent.log is clean but just the node that I restart the service "quantum-plugin-openvswitch-agent"and the other two node : get some error :

then depend wherre I restart the service I get gre-1 or gre-2

what else I need to check ?

find the problem http://techbackground.blogspot.co.uk/2013/06/path-mtu-discovery-and-gre.html

[rubber-ant]

fixed: sudo -s

touch /etc/quantum/dnsmasq.conf copy and paste "dhcp-option-force=26,1454 log-facility = /var/log/quantum/dnsmasq.log log-dhcp"

chown root:quantum /etc/quantum/dnsmasq.conf

add this line : dnsmasq_config_file = /etc/quantum/dnsmasq.conf

to /etc/quantum/dhcp_agent.ini

service quantum-dhcp-agent restart

@mseknibilel you should add that to the multiple node guide

this doesn’t have effect to cirros3.1 because it has a bug but it's working with ubuntu, fedora, debian..
