This video shows you how to install Citrix XenServer 5.5 on VMware Workstation 6.5. Though it’s not possible to run Virtual Machines inside XenServer it demonstrates how fast & easy it is to install. XenServer on VMware Workstation is also great for exam preparation & upgrade scenarios.
It´s a good example, but one thing: the message about no hardware virtualization found makes xenserver no functional.
