Hi All,
Has anyone managed to get guest customization of Windows Server 2012 working? From what I can tell it doesn't work at all. 
I am running the latest version of everything (vCenter 5.1, ESXi 5.1). I created a brand new VM, chose Windows Server 2012 as the guest type (which automatically makes it EFI instead of BIOS) and installed Windows Server 2012 and the guest tools - all working OK. I then shut down the guest and converted it to a template.
I am then deploying a new guest from the template and using a guest customization specification which I also created from scratch - the guest customization is very simple doing the standard stuff (like naming the OS the same as the guest, setting our company name and prompting the user for an IP address). Nothing fancy.
The new guest is created as expected and then I power it on. VMware obviously "injects" something into the OS at this point (like the sysprep file) and what is meant to happen is the OS boots up and then a minute or two later it reboots and does the sysprep routine with the injected sysprep file. This works fine with Windows 2008 R2.
With Windows Server 2012 it just sits there forever and never reboots - the guest customization simply doesn't run. If I logon to the server I can see that VMware has successfully created c:\sysprep and injected sysprep.xml and guestcustutil.exe into the folder. It just never actually uses them.
Any ideas? Is this working for anyone else?
Cheers,
David
