I have just started playing around with Vmware sphere and have the hypervisor OS installed on a spare HP ProLiant DL360 G4.

I have created a test virtual machine running Ubuntu which has worked well.

As a test project I wanted to convert a powered on server running Windows Server 2008 64bit into a virtual machine. As soon as I ran the Vmware Go software to start the conversion it became apparent that I cannot run 64bit guest OS's on that particular server.

So, is there a way of migrating 64bit to 32bit during the conversion?

There's not no, there's very significant differences between the actual code of the 64 and 32 bit versions, no converter will magically change this on the fly.

Is it possible to migrate the domain settings etc. to a pre-installed 32bit OS VM? –  dannymcc Jun 24 '11 at 22:20
    
Depends what you mean by "Domain settings etc". It's possible to create a 32 bit windows 2008 server install and promote it to be a domain controller in the same domain as the 64 bit host, if that's what you mean. –  RobM Jun 24 '11 at 22:27
    
I see, I forgot that promoting it to a DC would inherit the AD policies etc. Thanks! –  dannymcc Jun 24 '11 at 22:35

No, I don't believe there is any way to make that work.

I'm not familiar with the DL360 G4, is that not a 64bit CPU with VT instructions enabled? Any of the Core2 based Xeons (51xx series or better) should run 64bit guests.

From what I have read, VT support is not available sadly. –  dannymcc Jun 24 '11 at 22:36
