Finally, the memory and number of virtual CPUs needs to be allocated. When specifying the virtual memory there are options for the startup memory amount as well as the maximum memory amount. Total you cannot exceed more virtual memory than what is installed in the system. The number of virtual CPUs cannot also exceed the number of physical processing cores in the system. Depending upon your system specifications, you will want to adjust the virtual CPUs and memory accordingly. The system we used in this article was an octal-core setup with 4GB of FB-DIMM memory.
