So during the keynote at VMworld in Barcelona on Tuesday morning, 18 October 2016, VMware showed a demo of how a VMware Cloud infrastructure is stood up in AWS and following that, showed how a virtual machine was migrated with vMotion into the AWS hosted VMware Cloud. This seemed impressive. However, something’s been bothering me and I’ve been to the VMware booth to get an answer but came up short.

The question I have is around processor architecture. If I’m running Intel in my local vSphere environment and AWS/VMware decided to run AMD in the VMware Cloud on AWS, how would you get that vMotion migration to work? It can’t right?

Is there an option to select the processor vendor for the newly deployed VMware Cloud on AWS?

And we have an answer!! Thank you Alex Jauch (@ajauch)!

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.

Yesterday I had the unpleasant experience of having to go through my email to find an email I wrote back in February 2011 in which I detailed the steps required in order to perform an offline update of VMware ESXi hosts via PowerCLI. Had I posted the steps here on this site at the time, it would have saved me a lot of pain in trying to retrieve the email from an Enterprise Vault archive! So, as I have learned my lesson, I am posting the steps required to update ESXi from PowerCLI.

I've been working on the topic of replacing SSL Certificates for VMware vCenter and VMware Update Manager Server (VUM) for quite some time now. Earlier in May 2010, I had the privilege to consult a large financial institution in London on VMware and Virtualisation. The consultancy engagement was for only one week and one of my assignments was to create and document a procedure for replacing their SSL certificates on all of their very many vCenter and VUM servers. Now, at first when asked to this piece of work, I asked myself the question: "Other than maybe improving security, why would you want to replace these SSL certificates anyway?" I mean, the standard once generated when you install the vCenter and VUM servers seem to be working fine. However, the more I started to dig into their environment, the more I realised just why they wanted to replace the SSL certificates on these servers. Let me explain:

This article forms part of the Replacing vSphere SSL Certificates series.

Before continuing with the steps ioutlined in this article, be sure to have completed Step 3: Submit the new Certificate Request to a Certificate Authority

The rui.key and rui.crt files will be used by VMware products as replacement SSL Certificate files. However in addition to these two files a PFX-formatted certificate file called “rui.pfx” specific for Windows must be created. The “rui.pfx” file is a concatenation of the system’s certificate and private key, exported in PFX format.
