Release note added. If any revisions are required, please set the 
"requires_release_notes" flag to "?" and edit the "Release Notes" field accordingly.
All revisions will be proofread by the Engineering Content Services team.

New Contents:
When running RHEL-5 Virtualization on a machine with a large number of cores, it is possible for the hypervisor to crash during guest installation.  This happens because of a flaw during SMP bootup.

This was fixed by removing the offending code, since it wasn't really being used anyway.  It is now possible to reliably do guest installs on machines with a large number of cores.
