Help on network

[tyff49]

Hi, we work actually on ovirt since 2017 but we are not sure for the future of this solution. We need to validate that cloudstack is the right solution. I need some help on configuring the network.

First question : we don't need the public network, is it possible to skip it?

Second question : actually, our nodes have the following network :

• bond0 (active backup, 10g + 1Gb) on lan
  -> one vlan for management
  -> one vlan for storage
  -> multiples vlan for guest vm
• bond1 (lacp) on dmz with multiples vlan

Can i configure network on cloudstack in the same way and how ? I don't find any tutorial where management and guest network are on the same link with vlan tag.
Thank you for reading me and for your help, sorry for my english

Hey @tyff49, welcome to the CloudStack community!

I’m not a maintainer, just a fellow user, but I can help with your test environment.

Q1: Yes, you can treat the Public network as just another VLAN.

Q2: Your current node setup in CloudStack would look like this:

• Management VLAN (e.g., ID 1000)
• Storage VLAN (e.g., ID 1001)
• Guest VLAN range (e.g., IDs 1003–1100)

For the Public network, you can use either bond0 or bond1 (e.g., ID 1002), or even the native VLAN on whichever interface you prefer.

In short: your existing physical setup should work fine with CloudStack.

Can you help me on initial configuration of the node ? How do i have to configure the cloudbr0 and ip for management and storage ? On the other side, what do i should configure on the management web page for deploying initial zone/pod/cluster and node?

Have you some link where i can find case studio similar to my scénario?

Thank you

Here is how to deploy the management server https://docs.cloudstack.apache.org/en/latest/quickinstallationguide/qig.html#management-server-installation

Here is how you deploy the KVM host, if that is the hypervisor of your choice (recommended and simpler) https://docs.cloudstack.apache.org/en/latest/quickinstallationguide/qig.html#kvm-setup-and-installation

As soon as you have these steps completed, you will navigate to the WebUI and follow the Wizard for the creation of a new Zone and all the related resources (pods, clusters, storages, etc).

If you feel like a more structured learning experience, check out ShapeBlue's bootcamps https://www.shapeblue.com/cloudstack-training/

Note: I am not affiliated to them in any way, but they appear to produce and release a huge amount of free knowledge base on CloudStack.
