From a licensing perspective, virtualization is an issue related to CPU counting.
Virtualization is broadly defined as running more than one instance of an operating system on a physical server machine. This gives one physical server the ability to run multiple applications each inside of its own virtualized environment.
Each virtual environment that requires a FairCom DB Server must have its own server license. The FairCom DB Servers in each virtual environment can have unique user, connection, and CPU counts if desired.
On a machine running a VMware server or IBM's VIOS manager, the operating system of the virtual machine reports the number of processors assigned to the virtual machine, not the total number of processors on the physical machine. In turn, the FairCom DB server reports only the number of processors indicated by the operating system.
