Appendix: Add CPUs to the Security VM

If you have many guest VMs on a host, you should ensure that the Security VM has enough processing power to scan the files they use when they all start up.

To do this, add more CPUs for the Security VM. You can do this any time.

Note If you add CPUs after you put the Security VM in a computer group in Sophos Enterprise Console, you should wait until the Security VM complies with group policy.

Depending on the type of load, adding CPUs can also improve overall system performance.

Add CPUs in VMware ESXi

Add CPUs as follows:

  1. Power off the Security VM.
  2. In vSphere Client, select the Security VM.
  3. Select Edit Settings > Hardware > CPUs. Then specify the number of CPUs.

Add CPUs in Microsoft Hyper-V

Add CPUs as follows:

  1. Click Start, select Administrative Tools, and then click Hyper-V Manager.
  2. In the results pane, under Virtual Machines, select the Security VM.
  3. In the Action pane, under the VM name, click Settings.
  4. Click Processor and specify the number of processors.
