Edit vCenter Virtual Servers

You can edit CPU and RAM resources for all VSs. Depending on the OS it is built on, some VSs can have their CPU and RAM resized without needing to be powered off ("resize without reboot").

Windows 2008 and Windows 7 VSs can be resized without rebooting. With Linux, it depends on kernel. E.g. CentOS with kernel 2.6.18 can be resized; Ubuntu cannot. Whether a template allows resize without reboot is shown on the main Templates menu screen.

To adjust VS CPU & RAM resources:

  1. Go to your Control Panel's Virtual Servers menu.
  2. Click the label of the server you want to resize, to show its details screen.
  3. Click the Tools button and select the Edit Virtual Server link.
  4. Change label, CPU core/priority and RAM values, and click the Save button.

If the VS template allows resize without reboot, the resize should be completed automatically: you will be returned to the VS details screen and see a message indicating the resize was successful. If the template does not allow this, you will be asked to confirm that the VS will need rebooting so that the resize can take place.
