The Tag

The Tag used to create the VM-Topology consists of three elements and is stored as a single line in the notes field of a Hyper-V VM. Only one tag line is allowed per VM.

Elements

Environment

This tag element defines the VM-Environment the virtual machine belongs to. One VM has to belong to one environment and can belong to multiple environments. But it has to provide the same services in all environments and it has to depend on the same services in all environments.

Service

The service element defines the services provided by the VM for the environments it belongs to. A virtual machine can provide one or more services.

DependsOn

The DependsOn element includes all services a VM requires to be up in running before it can fully operate. For example, an Azure AD Connect server depends on the domain and internet access.

Syntax

A tag line looks like the example below. Multiple instances of an element are separated by a comma.

<pre><code>&lt;Env&gt;Environment1,Environment2&lt;/Env&gt;&lt;Service&gt;Service1,Service2&lt;/Service&gt;&lt;DependsOn&gt;RequiredService1,RequiredService2&lt;/DependsOn&gt;</code></pre>

You can create a tag by using the Set-VMTag command.
