In June 2007 a couple of brave virtualization experts published one of the most wanted trick for VMware: how to run VMware ESX 3.x on a VMware Workstation 6.0 virtual machine.
Now Xtravirt, the consulting company that sold its tools to PHD Virtual (formerly PHD Technologies), is back on the topic and releases new paper to run VMware ESX 3.5 or ESXi on a VMware Server 2.0 installation.
The trick is to change some settings in the virtual BIOS of the Server VM along with adding the usual configuration parameters in the VM configuration.
Considering that both Server 2.0 and ESXi are free this is going to be an instant classic.
