Different OpenStack instances on top of one infrastructure

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

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

use flatdhcp

That should work fine.
