ESXCLI Partner Extensiblity | VMware vSphere Blog - VMware Blogs - http://blogs.vmware.com/vsphere/2012/02/esxcli-partner-extensiblity.html
- by William Lam
- "Many vSphere administrators are familiar with the ESXCLI command-line utility that helps manage and configure settings on their ESX and ESXi hosts. With the release of vSphere 5.0, ESXCLI now includes a total of 250 commands that span across various namespaces. One would expect that VMware can easily extend and create new namespaces to expose VMware platform specific functionality. An example of this would be the vcloud namespace that is made available when vCloud Director is installed. What you may not know is, ESXCLI was actually built with a modular and extensible framework from the ground up and can easily be extended by third party providers as well."
- No instructions though!

Introducing the VIB Author Fling | VMware vSphere Blog - VMware Blogs - http://blogs.vmware.com/vsphere/2012/09/introducing-the-vib-author-fling.html
- "I’m very excited to announce the new vibauthor fling. This fling is hot off the press and provides the capability to create custom vSphere Installation Bundles (VIBs). Prior to this fling the VIB authoring tools were only available to VMware partners, this fling now extends this capability to everyone. There are a couple of use cases for creating custom VIBs. For example, if you are using Auto Deploy and you need to add a custom firewall rule to your host, or you need to make a configuration change that can’t be made using Host Profiles."
