At the moment we have a VMware template, which is already able to monitor standalone ESXi hypervisors, however, when using this template Zabbix essentially has to create two hosts, one where you attach the template which also will discover the hypervisor with the "Discover VMware hypervisors" discovery rule, you will end up with two hosts.
As highlighted by one of our customers, this can create issues with their ServiceNow integration, as they have to have two different hosts on the Zabbix GUI, and ServiceNow can only take one of them as a valid host with the correct hostname.

Attaching the "VMware hypervisors" template directly (which is a part of the VMware template as a whole), also does not work, as then there is a missing LLD macro that doesn't allow the template to function properly.
