Hi all,

I am following the guide that is provided by openstack themself: (, however I have 3 nodes each with one NIC, is it possible to install openstack using this setup if so how do I install the network part with just one NIC.

Thank you all

You may follows in general design from

    eth1 is eth0 
    eth2 is eth0
    On Controller/Network Node
    eth1 is eth0
    On Compute Node

Mgmt, VLXLAN tunnel ant External network should be the same

I would suggest plug in  Controller/Network Node second nic for External Network
for security reasons , avoiding network congestion for South/North packets forwarding 
and splitting South/North and East/West traffics
