You can change the virtual device node, the size of the disk, and the persistence mode for virtual disk configuration for a virtual machine.


Select a virtual machine.

In the virtual machines and templates inventory tree, select a group of virtual machines and select a virtual machine from the list on the right.

Search for a virtual machine and select it from the search results list.


In the VM Hardware panel, click Edit Settings.


Click Virtual Hardware.


Click the triangle next to a virtual disk to expand the disk options.


(Optional) To change the size of the disk, type a new value in the Provisioned Size text box and select the units from the drop-down menu.


(Optional) Select a disk mode.




Dependent disks are included in snapshots.

Independent - Persistent

Disks in persistent mode behave like conventional disks on your physical computer. All data written to a disk in persistent mode are written permanently to the disk.

Independent - Nonpersistent

Changes to disks in nonpersistent mode are discarded when you power off or reset the virtual machine. With nonpersistent mode, you can restart the virtual machine with a virtual disk in the same state every time. Changes to the disk are written to and read from a redo log file that is deleted when you power off or reset.


Click OK.
