These patches:
• Preserve entitlements in cases where a PRM group with a large entitlement and just
enough jobs to get that entitlement could be outperformed by a smaller entitlement
group with more jobs
• Improve performance of I/O-based applications when the Fair-Share Scheduler (FSS)
is enabled
• Address VERITAS Volume Manager (VxVM) errors that arise when PRM attempts
disk bandwidth control

Compatibility with HP Integrity Virtual Machines
HP Integrity Virtual Machines (Integrity VM) is a robust soft partitioning and virtualization
technology that provides operating systems isolation, shared CPU (with sub-CPU granularity),
shared I/O, and automatic, dynamic resource allocation. It is available for HP-UX 11i v2 running
on HP Integrity servers.
Given a system with Integrity VM installed, you can run PRM inside any of the virtual machines;
however, you cannot run PRM on the VM Host as the vm_fssagt already controls FSS groups
on behalf of Integrity VM.
NOTE: Do not specify disk bandwidth records for configurations used inside virtual machines.
Compatibility with processor sets (PSETs)
PRM allows you to define PRM groups based on PSETs.
