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
