Andrea, I wouldn't fix this bug, and we can probably close this bug using a tech-note that describes the limitations.
Andrea, Please take a look at Comment 1 and write a short tech-note. I will close this bug.
tech note from comment #1: win2008-64 guest boot correctly without -mem-path/hugetlbfs on RHEL5.9 host.
