Section 7 Optimizations
This section describes the optimizations required in virtual CPUs.
Virtual CPUs
As an initial guideline, it is recommended to have two virtual CPUs in each virtual
machine and to have at least one logical processor per virtual CPU. In some cases,
where there are a number of processes in the virtual machine which are consuming
high processor load, it may be necessary to add additional virtual CPUs to achieve
target performance levels.
To add an additional CPU to a virtual machine, it must first be shut down. The
hardware configuration is then edited, and the number of CPUs adjusted to the
required count. If a virtual machine has been configured with one processor,
Windows will use the uniprocessor kernel. When more than one processor is found,
Windows will then install the multiprocessor kernel and associated drivers. After
this installation, the virtual machine needs to be restarted.
To provide CPU resources to the virtual machines, there should be one logical
processor for each virtual CPU. For example, if the computer has 2 Quad Core
CPUs (8 cores) and each virtual machine had 2 virtual CPUs, then there should be
only 4 virtual machines running on the ESX(i) server (8 virtual CPUs).
Hyper threaded cores should not be counted as a single core since they share
resources with the core and do not provide the equivalent performance of two
cores.
