Usage

VP_KAIO_PERCENT is the percentage of total KAIO event resources on the system that each CPU VP will allocate.

If you set VP_KAIO_PERCENT to 10 and the total number of KAIO events configured in the OS kernel is 50000 then each CPU VP that starts will attempt to allocate 5000 events.

A value of 0 follows legacy algorithm for allocating KAIO resources to VPs.
