Comment 29 for bug 1302080

Tore, the debug output from the nova logs (cpu) would be most helpful, as that is where the brq device is created and configured.

And we did realize the qvb-* devices created on an OVS hybrid plug would auto-configure an IPv6 address since it would process the RA. But if the prefix assigned is only tenant-scope (i.e. some 2001:db8 prefix they are testing with) then there is not Internet reachability, it is mainly that the VM has access to the compute node.

I do not feel we need to worry about the tap devices, can the VM ping that address? And my single-node has disable_ipv6=1 on the taps, I don't know why you are seeing different yet.
