Re: Multi nic configuration documentation
[In reply to]
The command to enable multi nic is in the link you gave:
nova-manage network create --fixed_range_v4=18.104.22.168/24 --num_networks=1
--network_size=256 --label=test --project=$your-project
You most likely already used the "nova-manage network create" command to
create a network when initially installing OpenStack. This command just
creates a second network with a different subnet and ties it to one
particular project (--project).
That's all that is needed. When you launch a new instance in that project,
the instance will automatically have two NICs. You will most likely have to
manually enable the interface inside the instance as most cloud images are
only configured for one interface.
Regarding your question about public ips: to my knowledge there is not a
way to assign a public IP directly on the instance. It is always hosted on
the server running nova-network.
