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.

When a linked clone that is configured with a separate disk for the disposable files is powered off, View Manager 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.

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.

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.

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.
