The advanced multi-host virtual lab configuration can be used if your DR site is configured in the following way:
- VM replicas that you want to verify are located on different ESX(i) hosts.
- VM replicas that you want to verify are connected to one or several networks.
The advanced multi-host virtual lab leverages the VMware Distributed vSwitch (DVS) technology. For more information, see https://www.vmware.com/products/vsphere/distributed-switch.html.
When you configure an advanced multi-host virtual lab, you must select an ESX(i) host on which the proxy server will be created and DVS on which Veeam Backup & Replication will create isolated network(s).
Veeam Backup & Replication does not offer an option to automatically configure the DVS. The DVS must be pre-configured in your virtual environment.
DVS is limited to one datacenter. For this reason, all verified VM replicas and VM replicas from the application group must belong to the same datacenter. If VM replicas belong to different datacenters, you will be able to start them in the virtual lab but Veeam Backup & Replication will not be able to automatically verify them.
