vSphere 6 makes managing SSL certificates a lot easier than previous releases. It ships with its own Certificate Authority, (VMCA) that issues certificates for all components on your behalf, rather than having to replace each service certificate manually, or relying on self-signed certificates. This new VMCA comes with the Platform Services Controller (PSC) that can be installed as a separate appliance, or embedded within the vCenter Server installation or Appliance.

By default, the VMCA will self-sign its own certificate to be used as a CA certificate that will sign all requests for certificates. This self-signed CA certificate can be replaced by a certificate that is signed by a 3rd party root CA or your own root CA. Any certificate signed by the VMCA, which is an intermediate CA to your root CA, can then be validated by clients with the root CA and VMCA certificates installed.

As we are now busy doing P2V conversion of most of our physical servers I needed to use the Consolidation function in vCenter (previously known as VirtualCenter) to assess the workload of the physical servers (CPU and Memory Usage).

I was surprised to see that the "Consolidation" button disappeared from my VI Client! I checked if it was installed as a plugin and it was. I also checked if it was enabled and again, it was. However, the button was not there!

I found that although the plugin can be installed and enabled in the VI client, it is also a requirement to have VMware Capacity Planner installed on the vCenter server. I checked my vCenter server and confirmed that it was indeed already installed.

Here's the fix:

It seems like the Consolidation Function for vCenter is disabled by default in the vpxd.cfg file. To enable the consolidation function, do the following:

On the vCenter server, edit c:\Documents and Settings\All Users\Application Data\VMware\VMware VirtualCenter\vpxd.cfg
(I'm still using VirtualCenter 2.5.0 Build 119598, so your path could be ...\vCenter\cpxd.cfg? I'm not sure!)

You will find the following three lines:


Change them to read:



Restart the VirtualCenter service using the Services.msc MMC snapin in Windows. The Consolidation Button should now be available in your VI, Providing that that it's installed and enabled and that VMware Capacity Planner is installed on the vCenter server.
