Public bug reported:
Some background: I run a private cloud environment (folsom/stable,
FlatDhcp) in the 172.17.11.XXX/24 range. The private range for instances
is 192.168.100.XX/24 . Basically if I add a floating IP it get's
assigned from the 172.17.11.XX/24 range. Recently, I needed to assign
172.17.11.XX fixed addresses for local usage.
nova-manage network list
1 192.168.100.0/24 None 192.168.100.2 8.8.4.4
None None
3 172.17.11.224/28 None 172.17.11.226 8.8.8.8
None None
This should happen on the same bridge (br100).
Now when activating an instance with a fixed ip, /var/lib/nova/networks
/nova-br100.conf gets overwitten. So I end up with only the
172.17.11.XXX fixed ip in that list. While i would expect 192.168
addresses and 172.17.11 addresses. It seems that nova is not able to
handle multiple ipranges/dnsmasq on one bridge?
As a workaround I activated the network on a new bridge. I needed to
activate proxy_arp and change some iptables to make sure traffic gets to
the instance. Not something really maintainable :).
