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
