Want to see if its the VM? Rik van Riel has updated his 2.4-ac VM for new kernels and added reverse page mapping (a neat feature).
It is available at: http://www.surriel.com/patches/2.4/2.4.16-rmap-6
Give it a whirl, you might me impressed. If not, maybe we can scratch the VM as the problem and stare meanly at VFS ;-)
(Note my lock-break patch will fail on the new VM. Ignore it. The rest is still fine. Perhaps I'll do a lock-break for this VM later).
