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.
