l2 links between VMs (re-ask) [closed]
Hi,
Setup: RDO installation of Icehouse on Fedora 20; multiple compute nodes. Neutron is configured with VLANs.
Goal: Create layer 2 links between VMs
Problems:
- Can't boot instance on subnetless network Network ... requires a subnet in order to boot instances on. (HTTP 400)
- From horizon, can't launch instance with no security group (see also https://review.openstack.org/#/c/59578/ )
Question: How to [as easy as possible] bring this feature to the installation (connecting VMs with L2 links)?
It's another try ask the same question https://ask.openstack.org/en/question/12074/l2-links-between-vms/ (https://ask.openstack.org/en/question...) . Any hints are welcome.
Thanks a lot!
You need to create subnets to provide the layer 2 links. You can create subnets that don't use DHCP, but the subnets are what provide actual interfaces.
Thanks for your comment. Creating subnetwork requires me to specify IP version etc. which puts some layer 3 constraints. What I would need is pure l2 link -- nothing to do with IP.
Why did you need to ask a new question? Can you edit it so that it's more clearly different than the other one?
