What's Rich Brambley from VMETS is saying about Trainsignal's Videos:
“Train Signal’s VMware training provides invaluable resources for both a new VMware administrator and those who are preparing for the VCP certification. Besides completely covering how to administer a VMware infrastructure, David also does a great job presenting third party solutions that are widely used by the virtualization community.”
Here another free video from the course explaining the cloning process of a VMware Virtual Machine. Train Signal's VMware ESX Server course is over 17 hours of video training on VMware ESX Server. Enjoy.
