# How to Configure VM Computer Name Pattern Properties
A virtual machine computer name pattern can be assigned both for revertible and for persistent MED-V workspaces.
- Revertible—Administrators can assign a unique name to each revertible MED-V workspace instance to differentiate between multiple computers using the same MED-V workspace.
- Persistent—In a persistent MED-V workspace, administrators can set a computer to be renamed during a setup script.
## How to Assign a Virtual Machine Computer Name Pattern to a Revertible MED-V Workspace
**To assign a virtual machine computer name pattern to a revertible MED-V workspace**
1. Click the revertible MED-V workspace to configure.
2. In the **Revertible VM Setup** section, select the **Rename the VM based on the computer name pattern** check box.
3. In the **VM Computer Name Pattern** section, enter the pattern to use for naming virtual machine images, using the following options:
- **Constant**—Enter free text that will be constant on all computers using the MED-V workspace.
- **Variable**—Enter a variable, by clicking **Insert Variable**, and select from one of the following:
- **User name**
- **Domain name**
- **Host name**
- **Workspace name**
- **Virtual machine name**
The variable selected will be specific to the computer using the MED-V workspace. For example, if **Domain name** is selected, the unique name for each computer will include the computer's domain name.
- **Random characters**—Enter “\#” for each random character to include in the pattern. Each computer using the MED-V workspace will have a suffix of the length specified, which is generated randomly.
**Note**
The computer name has a limit of 15 characters. If the pattern exceeds the limit, it will be truncated.
4. On the **Policy** menu, select **Commit**.
**Note**
A revertible VM computer name pattern can be assigned only when **Rename the VM based on the computer name patterns** (in the **Revertible VM Setup** section) is checked.
~~~
**Note**
A unique computer name can be assigned only if it is configured prior to MED-V workspace setup. Changing the name will not affect MED-V workspaces that were already set up.
~~~
## How to Assign a Virtual Machine Computer Name Pattern to a Persistent MED-V Workspace
**To assign a virtual machine computer name pattern to a persistent MED-V workspace**
1. Click the persistent MED-V workspace to configure.
2. In the **Persistent VM Setup** section, click **Script Editor**.
3. In the **Script Actions** dialog box, click **Add**, and on the submenu, click **Rename Computer**.
4. Click **OK** to close the **Script Actions** dialog box.
5. On the **VM Setup** tab, in the **VM Computer Name Pattern** section, enter the pattern to use for renaming the computer, using the following:
- **Constant**— Enter free text that will be included in the computer name.
- **Variable**—Enter a variable, by clicking **Insert Variable**, and select from one of the following:
- **User name**
- **Domain name**
- **Host name**
- **Workspace name**
- **Virtual machine name**
The variable selected will be specific to the computer that is being renamed. For example, if **Domain name** is selected, the computer name will include the computer's domain name.
- **Random characters**— Enter “\#” for each random character to include in the pattern. The computer will have a suffix of the length specified, which is generated randomly.
**Note**
The computer name has a limit of 15 characters. If the pattern exceeds the limit, it will be truncated.
6. On the **Policy** menu, select **Commit**.
**Note**
The computer will be renamed only if it is set as an action in the **Script Actions** dialog box. For detailed information, see [How to Set Up Script Actions](how-to-set-up-script-actions.md).
