Host resources allow you to track information about the host machines for the workload VMs. You can use the Hosts page to create, edit, view, and delete host resources for the target workloads in your transformation project. You can define host resources for the source workloads when you import machine their machine data. A host resource can be used for source workloads or for target workloads, but not to both. A host resource for a physical machine can be assigned to only a single workload.
