Jon, CMS and z/VM are fully supported on IFL's. This is required in order to run Linux on System z under z/VM, since originally you could not define an LPAR that had both GCP's and IFL's defined to it. ============================================== Wayne Driscoll OMEGAMON DB2 L3 Support/Development wdrisco(at)us(dot)ibm(dot)com All opinions are mine, and do not represent IBM Corporation. ==============================================
