If you have an ISO image of VMware ESXi 7 hypervisor, you can create a template based on it in DCImanager 6:
In the platform interface, create a copy of any template in the location: Templates section → OS and operations templates tab → select any template → menu → Copy → specify an arbitrary name for the new template and the vmware tag → Copy button.
Copy the VMware ESXi 7 ISO image file to the location server.
Connect to the location server via SSH with superuser privileges.
Mount the VMware ESXi 7 ISO image to any directory. For example, /mnt/:
mount -o loop <path_to_iso> /mnt
BASH
Comments to the command
<path_to_iso> — path to ISO image
Go to the directory of the created template:
cd /opt/ispsystem/dci/os_templates/<template_name>
BASH
Comments to the command
<template_name> — created template name
