1. A method of sharing kernel services among kernels, the method comprising: receiving, by a partition manager from an application in a logical partition, a first system call for a kernel service from a first kernel, the first system call having form and content compatible with the first kernel; generating, in dependence upon the first system call, a second system call for the kernel service from a second kernel, the second system call having form and content compatible with the second kernel; and sending the second system call through the partition manager to the second kernel for execution.
