VMware DRS (Distributed Resource Scheduler) is a load balancing utility that assigns and moves computing workloads to available hardware resources in a virtualized environment. Active Directory Virtual Lab supports DRS clusters with Partly Automated or Fully Automated automation level.
Now in the ADVL console, you can specify a target host or a DRS cluster to create a virtual machine. For the DRS cluster, the target host will be selected automatically. The storage that is selected for the target virtual machine must be accessible from any host in the DRS cluster to successfully migrate the virtual machine.
The recommended network configuration for the DRS cluster is Distributred vSwitch connected to Virtual Local Area Network (VLAN). For more details, see the "network isolation at the infrastructure level" clause in Isolated virtual network and DNS.
If VLAN cannot be configured for the DRS cluster, you can use the host-only network configuration to ensure the network isolation. The host-only network configuration can be achieved by setting up virtual machine/host groups and affinity rules that allow you to disable the DRS cluster load balancing. To do so, create a host group that includes only one host and a virtual machine group that includes all virtual machines converted by Active Directory Virtual Lab. Then, you need to create a rule that assigns the virtual machine group to the host group using the affinity rule "Must run on hosts in group".
Recovery Manager for Active Directory Forest Edition provides an option to pause the lab creation process to perform all required actions before the virtual machine is turned on for the first time. To enable the pause option, set the HKLM\SOFTWARE\Wow6432Node\Quest\Recovery Manager for Active Directory\ADVL\PauseAfterCloning (DWORD) registry key to 1.
