I am running a nova-network node with FlatDHCPManager and 4 nova-compute nodes (one of them is also the nova-network node.

I have multiple networks on the nodes via vlans (eth1.101, eth1.102, etc) Which I also created inside openstack with this command:

nova network-create --fixed-range-v4 10.10.3.0/24 --vlan 102 --bridge br102 --bridge-interface eth1.102 --project-id 6e497c3118da4b8297c67f7f8e2d99d8 net102

All networks are created like the above example, with --project-id included.

Then when I create an instance inside a project, it get's fixed IPs from all created networks like this:

Shouldn't they get only from the asossiated project?

Is this a bug or am I missing something?

I also asked this here.

flatDHCP isn't intended to do any sort of network isolation... – Matt Joyce Sep 27 '13 at 20:07
I see... For this I have to use quantum/neutron ? – Stefanos Kalantzis Sep 28 '13 at 09:29
There is a vlan separation mode in nova-network in addition to flatdhcp called vlanmanager. – Matt Joyce Sep 30 '13 at 14:08
