Since the problem with running ESX 3.5 in Workstation 6 still isn’t fixed I tried to install ESX 3.5 in the beta version of VMware Server 2.0. What you have to do is de-install Workstation 6 and leave your virtual machine files present. Then download and install VMware server 2.0 and register the vmx file of your ESX 3.5 virtual machine. Just start it up and wait for a very long time (several hours). Eventually ESX 3.5 will become active and you should be able to start your Windows XP virtual machine. There is one but, The current virtual device type (e1000) is not supported by VMware Server e.x.p. I gathered some handy URL’s like Logon as Local Admin – Vista, Log on as builtin administrator in Vista and vmware beta 20 adds vista gutsy gibbon support. In the screen shot you see ESX 3.5 running within VMware Server 2.0.
