Hi OPNFV community,
I was reading the requirements to deploy a test environment of OPNFV. The
page I am using as a reference is the following:
http://artifacts.opnfv.org/compass4nfv/colorado/3.0/docs/installationprocedure/index.html.
I am starting to deploy the OPNFV for testing and I noticed the following:
Do we really need 16GB of memory for every VM that is going to play a role
such as OpenStack compute/controller nodes?
I mean, I am deploying a test environment for a single user. If I change
the parameter on “virtual.conf” file to 4GB (instead of 16), would it still
work? 16GB for every host VM seems too much; the server I am using has only
25GB of RAM and right now I do not have 3 servers for the bare metal
deployment.

Also, if I want to remove a host VM, can I just remove one entry from
“os-nosdn-nofeature-ha.yml”? Or is it a hard requirement to have at least 5
host VMs? For testing purposes, I do not think that I need two controller
nodes.
