Hi Miroslav/Fuel-Dev,

Kindly respond us with your suggestion at the earliest. Among 3 physical servers available, we are configuring Fuel Master in 1st physical server and we need help in configuring compute node and controller node in 2nd and 3rd physical servers.

Thanks and Regards,
Gandhi Rajan

Hi Miroslav,

Kindly find our setup details below and let us know your suggestion to form accurate setup for certification –

a) The number of physical servers you have for certification (I assume 2)
3

b) The number of network interfaces, available for tests on each physical server.
Physical Server 1 : 2 NICs
Physical Server 2 : 2 NICs
Physical Server 3 : 2 NICs

All 3 Physical Servers are attached to the Brocade VDX device.

Thanks and Regards,
Gandhi Rajan

Greetings Gandhi,
Virtualbox scripts do the following:
1. These scripts create everything  - virtual nodes and virtual networks - inside the same single physical host machine.
It is impossible to share the same virtual host-only network between different physical hosts, so the part of network is virtual and part is physical.

2. Virtualbox does not support virtual networks, distributed between several physical servers.

3. Virtualbox removes all VLAN tags for all the traffic, coming out from Virtualbox virtual networks to the physical networks.
These 3 Virtualbox limitations make completely impossible the scenario, where master node and controller are deployed as virtual machines on one physical server and compute node is deployed as bare-metal compute node on the second physical server.
Such setup is possible with QEMU/KVM, because of better VLAN support.
But this setup require sufficient quantity of physical network interfaces on the server, intended to host virtual machines with master node and controller.


You mentioned, you have only 2 physical servers under the hand.
Mirantis Openstack require at least 3 servers, one for master node, one for Openstack controller and one for Openstack compute.
However, for testing purpose it is possible to install master node to every cheap laptop or as virtual machine on a laptop, connected directly to the same network switch.
So, before I'll be able more specific, I would like to ask you kindly to describe in the following details all hardware you have got for the certification:
a) The number of physical servers you have for certification (I assume 2)
b) The number of network interfaces, available for tests on each physical server.
Having this information I'll be able to suggest more accurate test/certification setup.
Kind regards,
Miroslav

Hi,

We have two physical servers attached to Brocade VDX device. One is Fuel Master Node(already configured) and the second one is Compute Node.
We need guidance in configuring/setting up Compute node. Kindly let us know the configuration changes (config.sh), so that we will use second physical server as a compute node.

Our understanding is with the existing config.sh, on running launch.sh, Master node, controller node and compute nodes will again be created in second physical server as well whereas we required only Compute node to be installed in second server.

Thanks and Regards,
Gandhi Rajan
