Edit VM CPU and Memory Allocation

You can edit the number of CPU and memory shares allocated to a virtual machine to adjust its allocated resources. When you add resources, the appropriate amount of unassigned memory or CPU shares must be available for the operation to succeed. If values exist for the minimum and maximum allowed memory or CPU shares, any resource allocation change must stay within these limits.

You can also create and schedule policy with specific VM resource allocation actions.

To edit VM CPU and memory allocation

1. Open the Explore pane.

   Available groups, services, and systems appear.

2. Find and right-click a virtual machine on the Explore pane and select Configuration, Resource Allocation, CPU and Memory.

   The CPU and Memory Resource Allocation dialog appears.

3. Adjust the number of CPUs, reserved CPU percentage, and CPU Limit percentage.
4. Adjust the memory shares allocated to the virtual machine and click Ok after you edit all the details.

   A confirmation message appears.
