When you create a linked-clone pool, you can redirect the linked clones' guest OS paging and temp files to a separate disk. You must configure this disk to be larger than the paging file in the guest OS.

About this task

When a linked clone that is configured with a separate disk for the disposable files is powered off, View replaces the temporary disk with a copy of the original temporary disk that View Composer created with the linked-clone pool. This feature can slow the growth of linked clones. However, this feature can work only if you configure the disposable-file disk to be large enough to hold the guest OS's paging files.

Before you can configure the disposable-file disk, you must know the maximum paging-file size in the parent virtual machine. The linked clones have the same paging-file size as the parent virtual machine from which they are created.

As a best practice, you can remove the pagefile.sys file from the parent virtual machine before you take a snapshot, to avoid duplicating the file on all the linked clones. See Prepare a Parent Virtual Machine.

Note:

This feature is not that same as configuring local storage for the virtual-machine swap files. See Configure a Parent Virtual Machine to Use Local Storage.

Procedure

  1. In vSphere Client, right-click the parent virtual machine and click Open Console.
  2. Select Start > Settings > Control Panel > System.
  3. Click the Advanced tab.
  4. In the Performance pane, click Settings.
  5. Click the Advanced tab.
  6. In the Virtual memory pane, click Change.

    The Virtual Memory page appears.

  7. Set the paging file size to a larger value than the size of the memory that is assigned to the virtual machine.
    Important:

    If the Maximum size (MB) setting is smaller than the virtual-machine memory size, type a larger value and save the new value.

  8. Keep a record of the Maximum size (MB) setting that is configured in the Paging file size for selected drive pane.

What to do next

When you configure a linked-clone pool from this parent virtual machine, configure a disposable-file disk that is larger than the paging-file size.
