Hi @Xergy !

This info is missing from the wiki, I will add that, thanks for noticing.

1 - Add and remove machines

An AutomatedLab is defined by several XML files we export in the background. Those can
be modified to some extent by AutomatedLab cmdlets.

To remove a VM, import the lab first, then remove it:

Import-Lab -Name YourLab -NoValidation # NoValidation - fast import, because we don't need validation to run every time
Remove-LabVm -Name YourMachine # That is enough

To modify a deployment, either:

Import-LabDefinition -Name YourLab
Add-LabMachineDefinition -Name newMachine
Remove-LabMachineDefinition -Name AnotherMachine
Install-Lab

or add the machine definitions in your original script - AutomatedLab detects if a role has been deployed and skips it. As long
as you do not intend to change key settings, like the domain that is getting deployed, you can simply rerun the same script after
you have added a couple of machines.

2 - Deploy labs that use existing lab infra

Your scenario sounds like you would just do as in 1. and extend the existing lab. But, if you want to deploy a second lab, you can reuse components. In this case, AutomatedLab will not help you as much, so you will need to take care of networking, using the proper
domain credentials and so on.

The trick is to add certain roles using the SkipDeployment parameter. The Member Server in Lab 2 can be joined to the domain defined in Lab 1 by adding only a reference to the domain controller.

One example:

Lab 1 (Auto-generate everything):

New-LabDefinition -Name l1 -DefaultVirtualizationEngine HyperV
Add-LabMachineDefinition -Name DC1 -DomainName contoso.com -Role RootDc
Install-Lab

Lab 2 (Detect resources from lab 1 and reuse):

Import-Lab -Name l1 -NoValidation -NoDisplay
$net = (Get-Lab).VirtualNetworks
$domain = (Get-Lab).Domains
$dc = Get-LabVm -Role RootDC

New-LabDefinition -Name l2 -DefaultVirtualizationEngine HyperV
Add-LabDomainDefinition -Name $domain.Name -AdminUser $domain.Administrator.UserName -AdminPassword $domain.administrator.Password
Add-LabVirtualNetworkDefinition -Name $net.Name -AddressSpace $net.AddressSpace
Add-LabMachineDefinition -Name DC1 -DomainName $domain.Name -Role RootDc -SkipDeployment -IpAddress $dc.IpV4Address
Add-LabMachineDefinition -Name MS1 -DomainName $domain.Name -Network $net.Name -IpAddress $net.NextIpAddress()
Install-Lab
