+= Best practices when defining an {rh-rhacm}-discovered VM
+
+You can configure any VM in the cluster that is not an {rh-rhacm}-managed application as an {rh-rhacm}-discovered application. This includes VMs imported by using the Migration Toolkit for Virtualization (MTV), VMs created by using the {product-title} web console, or VMs created by any other means, such as the CLI.
+
+You can take several actions to improve your experience and chance of success when defining an {rh-rhacm}-discovered VM.
+
+Protecting the VM when using MTV, the {product-title} web console, or a custom VM:: Because automatic labeling is not currently available, the application owner must manually label the components of the VM application when using MTV, the {product-title} web console, or a custom VM.
++
+After creating the VM, apply a common label to the following resources associated with the VM: `VirtualMachine`, `DataVolume`, `PersistentVolumeClaim`, `Service`, `Route`, `Secret`, `ConfigMap`, `VirtualMachinePreference`, and `VirtualMachineInstancetype`. Do not label virtual machine instances (VMIs) or pods; {VirtProductName} creates and manages these automatically.
++
+[IMPORTANT]
+====
+You must apply the common label to everything in the namespace that you want to protect, including objects that you added to the VM that are not listed here.
+====
+
+Including more than the `VirtualMachine` object in the VM:: Working VMs typically also contain data volumes, persistent volume claims (PVCs), services, routes, secrets, `ConfigMap` objects, and `VirtualMachineSnapshot` objects.
+
+Including the VM as part of a larger logical application:: This includes other pod-based workloads and VMs.

+= Best practices when defining an {rh-rhacm}-managed VM
+
+When creating an {rh-rhacm}-managed application that includes a VM, you must use a GitOps workflow and create an {rh-rhacm} application or `ApplicationSet` resource.
+
+You can take several actions to improve your experience and chance of success when defining an {rh-rhacm}-managed VM.
+
+Use a PVC and populator to define storage for the VM:: Because data volumes create persistent volume claims (PVCs) implicitly, data volumes and VMs with data volume templates do not fit as neatly into the GitOps model.
+
+Use the import method when choosing a population source for your VM disk:: Select a {op-system-base} image from the software catalog to use the import method. Red{nbsp}Hat recommends using a specific version of the image rather than a floating tag for consistent results. The KubeVirt community maintains container disks for other operating systems in a Quay repository.
+
+Use `pullMethod: node`:: Use the pod `pullMethod: node` when creating a data volume from a registry source to take advantage of the {product-title} pull secret, which is required to pull container images from the Red{nbsp}Hat registry.
