Thread-topic:
[Openstack] quantum-openvswitch-agent needs a restart to bind the vlan-ID
Hi Dan,
This issue happens only when rpc = True and it happens consistently. When rpc =False, everything is fine. Thanks for this pointer!. Also, I am just spinning up a single VM though the horizon interface without using any scripts.

Hi Naveen,
Was noticing something like this while testing last night, but hadn't gotten around to determining if it was in master or just the branch I was testing.
Are you seeing this even if rpc = False? I noticed this only when my
settings got reset to make rpc = True, though I haven't investigated it enough to know if that is the rpc flag is just a coincidence.
Another possible correlation I've noticed is that it occurs when I use a script to spin up multiple VMs in succession, possibly suggesting some kind of race/timing issue. Does that match your use case?
It looks like there's a bug on this, so I'll post my questions there as well, so that we can keep all info on the bug in one place:

Thanks,
Dan
