It’s a light second Rollup update for the product, patching just two issues. One only affects a managed Hyper-V cluster that has HP Cluster Extension Software installed.

The second and last fix patches the Self-Service Portal, which in some cases would not display all virtual machines if the user had 50 or more machines assigned.

The VMM 2008 R2 SP1 was last patched in July of last year, and this Rollup includes those previous fixes.
