use flatdhcp

That should work fine.

Status: Answered => Open

TMB is still having a problem: Thanks, Vish. But I am not perfectly sure I understand it fully.

Setup: 1 router/mgt-host <-> 1 switch <-> 15 workers

The mgt host is used for non-OpenStack related issues, it acts in particular as router (gateway) to the public internet. Idea was configure 3 vlans to divided the 15 nodes into three complete OpenStack instances (1 master/worker, 4 workers)

Would that work? Which network mode do I use for the three instances?

And what in case my switch (HP ProCurve 2910 AL-48G) does not support "host-managed VLan"?

Thanks, TMB

Yes, that would work.

You might consider an extra vlan per deploy, or potentially 3 if they are available to the public network vlan1 -public ips vlan2 -mgmt ips vlan3- vm ips

Folks,

Assume: 15 nodes connected through on switch.

Aim: 3 parallel OpenStack instances (one productive, one for testing, one experimental) are supposed to be deployed on top of the single infrastructure 5 nodes per OpenStack instance.

Idea: Isolation on L2, dividing the LAN into 3 L3 domains, e.g. via VLan. Run one OpenStack instance per VLan.

Question: Would that work?

Thanks, Both
