I’m using nova-network with Havana and noticed an odd thing when creating
networks. When I create a network, either with “nova network-create” or
“nova-manage network-create”, the VLAN number I specify isn’t being used.
Instead, it seems to be assigning only odd-numbered VLANs, which is causing my
numbering to be off. This is causing me problems, because I haven’t tagged
those random VLANs on my equipment.
For example, the following command caused this network to be added with br811
and vlan811 bridge and interface instead of the expected br806 and vlan806:
# nova network-create —fixed-range-v4=10.14.126.0/24 —vlan=806
--dns1=10.14.4.21 --project-id=fbb371b9c5cb4f849c40a45eaacc4457 my_new_tenant
# ifconfig -a
…
br811 Link encap:Ethernet HWaddr FA:16:3E:9E:89:64
inet addr:10.14.126.1 Bcast:10.14.126.255 Mask:255.255.255.0
vlan811 Link encap:Ethernet HWaddr FA:16:3E:9E:89:64
UP BROADCAST RUNNING MASTER MULTICAST MTU:1500 Metric:1
# nova-manage network list
id IPv4 IPv6 start address DNS1
DNS2 VlanID project uuid
…
7 10.14.126.0/24 None 10.14.126.3 10.14.4.21
None 811 fbb371b9c5cb4f849c40a45eaacc4457

This does not happen with my Folsom installation. Any help would be
appreciated.
