Avanti requires a minimum of 2 host server CPU cores.  One CPU is dedicated to emulating the Alpha CPU and will run at 100% when Avanti is active.  Plan adequate VM resources to support this requirement.

It is important to allocate sufficient CPU resources on a VM to support Avanti.  If a VM manager throttles CPU resources to a VM hosting Avanti, poor performance and slow clock speeds resulting in time drift will occur.  Recommend best practice is to put a CPU reservation on the Avanti host VM such that two full CPUs are always available to the Avanti system.  I.e.: if running on a VM host equipped with 3.0GHz CPUs, reserve 6000MHz of CPU to the host.
