Open Stack

Recently, I figured out that, when using Ubuntu 14.04 + QEmu 2.0 (KVM), you
can not use the KSM (Kernel Samepage Merging) and run W2k8 R2 at the same
time, take a look:

Ubuntu 14.04 + QEmu 2.0 + KSM = 1, makes Windows 2008 R2 guests to crash
(BSOD)

This problem will affect all OpenStack Icehouse clouds based on Ubuntu
14.04 out there...   :-/

I was planning to use Xen (apt-get install xen-system-amd64) instead of KVM
but, replacing a hypervisor at a OpenStack Compute Node isn't trivial, so,
I just disabled KSM...
