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, Protection and OS page:
   1. Type the Name and an optional Description for the VM as they will appear in the everRun Availability Console.
   2. Select the level of protection to use for the VM:
      • High Availability (HA) — Provides basic failover and recovery, with some faults requiring an (automatic) VM reboot for recovery. Use HA for applications that can tolerate some downtime and that do not need the downtime protection that FT provides.
      • Fault Tolerant (FT) — Transparently protects an application by creating a redundant environment for a VM running across two physical machines. Use FT for applications that need greater downtime protection than HA provides.

      For more information about these levels of protection, see Modes of Operation.

   3. Click Next.
5. On the Volumes page, you can:
   Note: You cannot modify the VM boot volume, only data volumes.
   • 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.) Specify the Name, Size, and Storage Group for the new volume.
   • Click Detach to disconnect a volume from a VM and keep it for future use.
   • Click Delete to permanently remove a volume from the everRunsystem.
   • Select an unattached volume from a pulldown menu (if displayed) and click Attach.

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

6. On the Networks page, select the shared networks to assign to the VM. For more information, see Planning Virtual Machine Networks. To continue, click Next.
7. On the vCPUs and Memory page, 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. 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 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.
