I'm trying to set up a minimal platform with Airship inside VMs (yes nested virtualization in the air...) and I succeed to install a Genesis node on a VM m1.xlarge (8vCPU/16GB Ram/160GB HDD) with Airship-in-a-bottle / dev_minimal Procedure.

As no minimal config SITE is defined can someone tell me:

1. if it is possible to use other VM which are playing the role of Controller/Worker Nodes to deploy a Site on ? That is no ILO/IDrac capability

2. What is the strict minimum number of Nodes (1Genesis + 1 Controller + 1 Compute) and resources ? 

I found these requirements https://airship-treasuremap.readthedocs.io/en/latest/authoring_and_deployment.html?highlight=shipyard#hw-sizing-and-minimum-requirements 

24 vCPU are really needed for a Controller Node or could the Genesis also play this role ?

What is the minimum for a Compute Node out of the Application layer usage?

Thanks in advance.

BR,
