At the Recovery Location step of the wizard, select a location to which VMs groups included in the plan will be restored.
For a recovery location to be displayed in the list of available recovery locations, it must be created and included into the list of plan components available for the scope, as described in section Managing Recovery Locations.
For the test to run successfully, you must map isolated networks of the virtual lab to all target networks present in the network mapping table of the selected recovery location. In case you want any of the recovered VMs to be connected to the same networks as the source VMs, you must map isolated networks of the virtual lab to those source networks.
To do that, configure the Isolated Networks settings of the virtual lab in the Veeam Backup & Replication console, as described in the Veeam Backup & Replication User Guide, section Recovery Verification.
Even if you have selected the Quick test option at the Test Options step of the wizard, you can still select a location which has Instant VM Recovery disabled. The test will still be able to run successfully using the sandbox Instant VM Recovery environment.
