Comment 1 for bug 1001584

Please see

http://wiki.debian.org/Hugepages

and

http://www.linux-kvm.com/content/get-performance-boost-backing-your-kvm-guest-hugetlbfs

for more info on how to use hugepages. In particular, if you need exactly
4400 pages (8.8G) for your guest, then do reserve some extra pages for
overhead.

Unless that solves your problem for you, could you please have your system
provide some debugging information using

sudo apport-collect 1001584

on the server?
