I have an issue regarding network in my VMs. I have a fresh install with RDO on 2 compute node.

I can SSH into VM I created, but once there, I can't download anything.

With a windows virtual machines, I was able to see the website http://perdu.com but no other website, so I changed the MTU with a greater value (2500) and it seemed to fix the issue.

On linux (debian 8.3), "ip set link dev eth0 mtu 2500" does not work.

Could anyone guide me through debugging this ?

Could you elaborate which node which OS is running ?
What kind of set up ? (Say ML2&&OVS&&VXLAN or some other )

Hosts are running CentOS 7 I'm running last version of RDO according to https://www.rdoproject.org/install/quickstart/ (https://www.rdoproject.org/install/qu...)

This installation is using openvswitch for networking purpose. I adjusted the floatingIP range to fit my network.

@Gentux - This issue has been open for almost a year. Is it something that you're still experiencing with a current release of OpenStack?
