HP-UX Virtual Partitions Administrator Guide (includes A.05.07) (5900-1229, September 2010)

For example, if we calculated the size of the kernel of the first OS to be 64 MB and the second
OS to be 128 MB, the sum is 192 MB. 192 MB is below the 2 GB limit, so we have met the criteria
and can migrate the OSs from the multiple non-vPars servers to the single vPars server.
NOTE: For vPars A.04 and later, you will need to accommodate for your granularity setting
by rounding memory usage to the granularity boundary.
