Hello,

I just begin with OpenNebula, and I’m lost for the network configuration.
I’ve 4 hosts and I’ll have a lot of VM running on them.
We’ll use OpenNebula to manage our training virtual infrastructures (we’re teachers).

For example, we’ve infra for the pentest cursus. This means 10 VMs for each students groups.
Within each infra, there is a fw and several subnets. I’d like to separate all the subnets trough VLAN. I guess the best is to use the vnet openvswich, but I’m lost with this.

Can someone give me some hints ?

Thanks in advance,
Benjamin

Hello @benjavd,

Hope we can help you.

As a starting point, yes, the VLANs and Open vSwitch can be difficult to set up at the beginning, I would suggest to check our documentation:

You will need to install OVS in all hosts, and create bridges on each host to communicate with the VMs. Also, you’ll need to create VNETs for each VLAN, and assign VNETs to VMs.

In any case, I guess that with the links to the documentation, all these steps are explained, and if you are stuck with something, feel free to let us know.

Cheers,
