When a thread is run in a user defined virtual processor, a virtual-extension segment is created. In the output of the onstat -g seg command, the virtual-extension segment has a class of VX. If the EXTSHMADD configuration parameter is not set in the onconfig file, the size of virtual-extension segments is set by the value of the SHMADD configuration parameter.
