Avanti requires at least two allowed host logical processors: one affinity claim for the Alpha-CPU thread and at least one remaining processor for I/O work. The Alpha-CPU thread can run at 100% while Avanti is active. Its affinity claim does not reserve a physical core from Windows or other applications. 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.
