Open Stack

Hi,

I have two hosts in my openstack setup: blade03 and blade04. I have set up my openstack with vlanned networking. The instances are being created on the specifed vlans correctly.

The problem is that I cannot ping instances on blade03 from blade04. I can ping blade04 instances from blade04. I do not expect to be able to ping blade03 instances because the nova network service is not running there.

I have experimented to make sure vlans are working on the switch. I created a new vlan interface on blade03 and blade04 and pinged between them quite happily.

What am I missing?

Thanks,

Andrew
