Create VM from ISO on scale 25

I am trying to create a new virtual machine from iso in scale 25 but not sure if I am doing something wrong becuase there is no way to access to installation process booting VM from ISO provided. No way to access using VNC and shell or serial show an error.
What is now process to attach and ISO for linux installation and be able to install OS?
Thanks!

Right now there’s no way to point the installer to an iso that’s already on the nas, there should be an option to upload an iso, which then can be used to install the os of your choice on a new vm.
