How to hot add memory on a virtual machine with Performance Cloud powered by VMware

TABLE OF CONTENTS

Description

The Memory hot add feature allows you to add memory resources (RAM) for a virtual machine while that virtual machine is powered on.

Please make sure to have enough resources in your virtual Data Center before trying to add resources on virtual machines. If needed, add required resources in your account management portal Cumulus.
When you enable the CPU hot add feature, vNUMA is automatically disabled for the VM. By default, vNUMA is enabled for all VMs that have 8 vCPUs or more to improve performance. Please review this article for more details on NUMA.
Guest operating systems that support Hot Add are Windows Server 2003 and newer, and Linux using kernel 3.8 and above.

Login to the Performance Cloud VMware portal using your credentials.
Click on your Virtual Data Center (vDC)
Optional but strongly recommended – Have latest VMware tools available installed in the virtual machine. Please review this online article on how to update VMware tools on virtual machines.
Go into the Virtual Machines section and identify your virtual machine.
Shutdown the virtual machine.
Open the virtual machine details.
Under Hardware, go into the Compute section.
Then, click on EDIT.
Toggle the Memory hot add button to enable the feature.
Then, click on SAVE.
Notice that the Memory hot add feature is now enabled.
Then, power on the virtual machine.
The virtual machine is now ready if you want to add more memory later while the virtual machine is running.
