Changing SMP HAL to use a UP HAL Windows 2008 and 2007

That is pretty clear as well. If you are looking to reduce the number of vCPUs being utilized in your environment don’t expect a reboot to be all that is required to have the VM running in uniprocessor mode.

Forcing Windows 2008/2008 R2/7 to redetect and use an appropriate HAL for the number of vCPUs it has been allocated or has been changed is a pretty simple affair:

Execute MSConfig, and then go to tab Boot -> Advanced Options…, check option “Number of Processors”, change the number to # of vCPUs being utilized.

Or using command line:

Creating a VMware Template for Windows Server 2008R2 using the Windows AIK

I’ve been experimenting with creating a good Windows Server 2008 R2 template for VMware vSphere 4 and wondered just how many times Microsoft would allow an activation on the same MSDN license key (Multiple Activation) for the OS.  I often deploy multiple servers at a time and am always fearful of activating since I don’t want the key to be shut off.  Typically I only run these servers for short periods of time so not activating is no big deal, however in longer running projects I often have no choice but to either activate or destroy and redeploy.  With information that I’ve come across on
