How to configure Openstack on multiple physical servers?

asked 2014-06-04 12:18:07 -0500

anonymous user


From the book "OpenStack Cloud Computing Cookbook", I find that all the installation of the openstack is on VMs. I am wondering is it possible to install the openstack directly on physical servers without VMs?

Actually, by installing openstack on VMs, the situation is that when I install the compute node (Nova) on the VM of server 1, I cannot use it to manage the resources on server 2.

Is there any way I can use openstack to manage a large quantity of physical servers instead of VMs?

Thanks in advance!

Sure you can , view for instance 1. Two Real Node (Controller+Compute) RDO IceHouse Neutron OVS&VLAN Cluster on Fedora 20 Setup , 2. Two Real Node (Controller+Compute) IceHouse Neutron OVS&GRE Cluster on Fedora 20 In general 3 Real Node Setup is recommended Controller,Neutron Server, Compute Node ( or several Compute Nodes). View for instance RDO Hangout by Larsks or for Devstack - OpenStack in a realistic test configuration with multiple physical servers

Thanks a lot for the quick response and useful information.

From the solution, I find that they configure the network for the two nodes as :

icehouse1.localdomain - Controller ( icehouse2.localdomain - Compute (

Mostly, these are two VMs. Suppose they are installed on two physical server , how do they communicate with each other using the private network?

In my blog they communicate with each other via . This is management && public network at a time based on public interfaces p37p1.
Interfaces p4p1 support either VLAN (1) or GRE tunnel (2) ( both are set to promiscuous mode ).
In GRE case this is network

That makes sense and Thanks a lot!
