+The Palette Virtual Machine Orchestrator (VMO) pack consolidates all components that you need to deploy and manage
+Virtual Machines (VMs) alongside containers in a Kubernetes host cluster. You can deploy VMO as an
+[add-on cluster profile](../profiles/cluster-profiles/create-cluster-profiles/create-addon-profile/create-addon-profile.md)
+on top of an existing data center or edge cluster.
+
+![Diagram that explains the architecture behind Palette VMO.](/vm-management_architecture_vmo-architecture.webp)
+
+## Palette VMO Components
+
+By default, Palette VMO includes the following components:
+
+- **Descheduler**. Enables VM live migration to different nodes in the node pool when the original node is in
+  maintenance mode.
+
+- **Snapshot Controller**. Enables you to create VM snapshots. This component is automatically installed when you
+  initiate or schedule cluster backups.
+
+  :::info
+
+  Palette installs a snapshot controller into every cluster where backups are scheduled or have been created on-demand
+  in the past. To prevent resource conflicts, you can disable the VMO snapshot controller in the pack YAML
+  configuration.
+
+  ```yaml
+  charts:
+    virtual-machine-orchestrator:
+      snapshot-controller:
+        enabled: false
+  ```
+
+  :::
+
+- **Spectro VM Dashboard**. Enables you to create, manage, and monitor VMs from Palette. The dashboard becomes available
+  once the VMO pack is successfully deployed as part of your cluster profile.
+
+- **KubeVirt**. This open-source solution enables you to create and manage VMs within Kubernetes clusters. KubeVirt
+  extends Kubernetes with additional virtualization resource types using Kubernetes Custom Resource Definitions (CRD)
+  API.
+
+  With KubeVirt, you can use the Kubernetes API to manage VM resources in the same way you would manage standard
+  Kubernetes resources.
+
+  :::tip
+
+  Palette VMO is pre-configured to use a number of KubeVirt feature gates out of the box, and you can configure
+  additional feature gates as necessary. Refer to the [Feature Gates](#feature-gates) section for more information.
+
+  :::
+
+- **KubeVirt CDI**. Provides persistent storage for Kubernetes clusters and enables the use of Persistent Volume Claims
+  (PVCs) as disks for KubeVirt VMs.
+
+- **Volume Snapshot Controller**. Watches VolumeSnapshot CRD objects and manages the creation and deletion of volume
+  snapshots. A snapshot represents a point-in-time copy of a volume.
+
+- **Multus CNI**. Enables multiple network interfaces to attach to Kubernetes pods. In the context of VMO, Multus
+  Controller Network Interface (CNI) automatically creates VLAN interfaces onto which you can place VMs.
+
+### Feature Gates
+
+Palette VMO includes the following KubeVirt feature gates by default:
+
+- LiveMigration
+- Snapshot
+- HotplugVolumes
+- VMExport
+- ExpandDisks
+- HotplugNICs
+- VMLiveUpdateFeatures
+- [CPU Hotplug](./create-manage-vm/enable-cpu-hotplug.md)
+
+For more information on KubeVirt feature gates, refer to the
+[KubeVirt Activating feature gates](https://kubevirt.io/user-guide/cluster_admin/activating_feature_gates/) guide.
+
+## Next Steps
+
+Now that you understand the architecture behind Palette VMO, you can continue exploring it by reviewing our
+[Environment Setup](./environment-setup.md) and [Create a VMO Profile](./create-vmo-profile.md) pages.

+
+A VM clone is a copy of an existing virtual machine (VM). The cloned VM has the same configuration settings and
+identifiers as the parent VM. After you clone a VM, the cloned VM acts as a separate virtual machine.
+
+Cloning is a quick way to create a new virtual machine that shares the same properties as the parent. You may want to
+clone a VM for the following reasons:
+
+- Software testing. Developers can clone an active VM to test new changes to their code.
+
+- Forensics. Security administrators can clone an infected machine and connect it to an air-gaped network to investigate
+  the source of the infection while the parent VM can be destroyed or remediated.
+
+## Prerequisites
+
+- An active cluster in Palette with the Virtual Machine Orchestrator (VMO) pack.
+
+- Outbound internet connectivity for port 443 is allowed so that you and your applications can connect with the Spectro
+  Cloud reverse proxy.
+
+- Users or groups must be mapped to a Virtual Machine RBAC role. You can create a custom role through a manifest and use
+  Palette's RoleBinding feature to associate users and groups with the role. Refer to the
+  [Create Role Bindings](../../clusters/cluster-management/cluster-rbac.md#create-role-bindings) guide to learn more.
+
+- A namespace for VMs. Although you can deploy VMs from the default namespace, we recommend creating at least one
+  namespace dedicated to VMs as a way to organize and manage them. To learn how to create a namespace, check out
+  [Create a Namespace](../../clusters/cluster-management/namespace-management.md#create-a-namespace).
+
+## Clone a VM
+
+1. Log in to [Palette](https://console.spectrocloud.com).
+
+2. From the left **Main Menu**, click **Clusters** and click on your cluster.
+
+3. Click on the **Virtual Machine** tab.
+
+4. Select the VM to clone and click either the **three-dot Menu** or **Actions**.
+
+5. Power off the parent VM and click **Clone**. If you forget to power it off, the parent VM will automatically be
+   powered off while cloning is in progress.
+
+6. Give the clone a name, an optional description, and select a namespace.
+
+7. Optionally, you can enable the checkbox to start the cloned VM automatically when cloning is complete.
+
+## Validate
+
+From the **Virtual Machines** tab, verify the cloned VM is listed and displays **Running** status.
