Reprovisioning Virtual Machine Resources

Reprovision a virtual machine (VM) to change its allocation of virtual CPUs (vCPUs), memory, storage, or network resources.

Launch the Reprovision Virtual Machine wizard by clicking Config in the bottom pane of the Virtual Machines page. The wizard steps you through the process of reallocating resources to the VM.

To reprovision a virtual machine

1. Open the Virtual Machines page (see the Virtual Machines Page).
2. Select a VM and click Shutdown.
3. When the VM has stopped, click Config to display the Reprovision Virtual Machine wizard.
4. On the Name, Description, and Protection page:

   1. Type the Name and an optional Description for the VM as they will appear in the ztC Edge Console

      The VM name must meet the following requirements:

      • A VM name must start with a word or a number, and the name cannot include the special characters (for example, #, %, or $).
      • A VM name cannot use hyphenated prefixes such as Zombie- or migrating-.
      • A VM name has a maximum of 85 characters.
   2. Select the level of protection to use for the VM:
      • Fault Tolerant (FT)
      • High Availability (HA)

      For information about these levels of protection, see Creating a New Virtual Machine and Modes of Operation.

   3. Click Next.

5. On the vCPUs and Memory page:

   1. Specify the number of vCPUs and the amount of Memory to assign to the VM. For more information, see Planning Virtual Machine vCPUs and Planning Virtual Machine Memory.
   2. Click Next.

6. On the Volumes page, you can:
   Note:

   You cannot modify the VM boot volume, only data volumes. However, you can detach the boot volume.

   • Click Boot Volume to detach the boot volume.

     Caution: If you detach the boot volume, the VM becomes unbootable.

     A warning appears saying that detaching the boot value causes the VM to become unbootable. If you want to undo detaching the boot volume, click Undo Detach.

   • Click Detach to disconnect a volume from a VM and keep it for future use.
   • Click Delete to permanently remove a volume from the ztC Edge system.

   • Select an unattached volume from a pulldown menu (if displayed) and click Attach.

     You can also, if applicable, click Add New Volume to create a new data volume. (If the button is not visible, scroll down to the bottom of the wizard page.)

     For an unattached volume or a new volume, specify the volume's parameters:

   1. Type the Name of the volume.

   2. Type the Volume Size of the volume in gigabytes (GB). For more information about allocating storage, see and Planning Virtual Machine Storage.

   3. If applicable, click Attach to connect a volume to a VM.

   To continue, click Next.

7. On the Networks page, activate the check box for each shared network that you want to attach to the VM.

   For each shared network that you attach, you can also optionally:

   • Set a custom MAC address (for details, see Assigning a Specific MAC Address to a Virtual Machine).
   • Set the State to Enabled or Disabled, which allows you to allow or block network traffic to the selected network.

   For more information, see Planning Virtual Machine Networks. To continue, click Next.

8. On the Configuration Summary page:

   Caution: Make sure that any volumes marked for removal are correct. When you click Finish, permanent data loss occurs on disks marked for removal.
   
   1. Review the configuration summary. If you need to make changes, click Back.
   2. To accept the VM as provisioned, click Finish.
9. Click Start to restart the VM.
10. For Windows-based VMs, if you changed the number of assigned virtual CPUs in a Windows-based VM from 1 to n or n to 1, after restarting the VM at the end of the re-provisioning process, you must shut down and restart the VM a second time. This allows the VM to correctly reconfigure itself for Symmetric Multiprocessing (SMP). The VM displays odd behavior and is not usable until it is restarted.
