[rhos-list] tenant_network_type vlan not working on RHEL 6.4/RDO

Hi,

Two things:

1. Your host needs at least one "vlan interface" up, otherwise packets get dropped. This is an bug in rhel/centos 6.4. The vlan itself does not really have to exist.
Common workaround is to set up a dummy vlan interface on the physical interface transporting the VLANs. Dummy meaning here a nonexistent, like:

cat /etc/sysconfig/network-scripts/ifcfg-ethX.666
DEVICE=eth1.666
ONBOOT=yes
TYPE=Ethernet
VLAN=yes

I guess this is what you are experiencing when adding a eth4.40.

2. AFAIK you need to have

use_veth = True

in your quantum.conf

Documentation on that is a little bit lacking last time I checked.

hf,
