Hello @Gilles B 

Using Prism Central, you can install NGT on multiple VMs without the need to manually mount the iso. 

This post might guide you in the right direction.

Hi @Gilles B for now NGT iso is generated on demand and is not available as a standalone iso. this is a future feature and is on the roadmap - will add your request there too. 

NGT communicates through a secure channel to CVMs in the cluster - which is why when the iso is generated there are virtual machine related details as well which are included - to establish a secure channel.

we will inquire further and see if there is any change and if your scenario is supported.

you can explore the nutanix.dev api reference and see if you can utilise some rest api calls to invoke NGT install after the VM deployment.
