Hello!
Your part one did it. Grmbl, what a Stoopid(tm) bug.
Many thanks, I owe you a beer.
I have ovs_use_veth = True set in /etc/quantum/quantum.conf, that seems to do it for all parts of Quantum/Neutron.
Best regards / Mit freundlichen Grüßen
Lutz Christoph

(not quoting question, because of HTML)
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,
Michael Luksch
