is the ksm control daemon running ('ksmtuned')?, If not, start with:

# /etc/init.d/ksmtuned start

As an additional note, I am running 8 VMs on this box.  4x Ubuntu 9.10 Server, 3x Windows Server 2003, and 1x Windows XP.

Hi Dietmar,

That doesn't appear to be the issue:
vm0:/# free
             total       used       free     shared    buffers     cached
Mem:       8180404    8129008      51396          0      95952    2316360

Anything else I should try checking out?

KSM only starts when you use more than half of your physical memory.

I have just started testing KSM and it doesn't appear to be working on my server.  ( 0 shared pages )

I have verified that the kernel is configured to boot with the option enabled, and I show the ksmd process running.

vm0:/# pveversion -v
pve-manager: 1.5-1 (pve-manager/1.5/4561)
running kernel: 2.6.32-1-pve
proxmox-ve-2.6.32: 1.5-2

vzquota: 3.0.11-1
pve-qemu-kvm: 0.11.1-1

Any ideas of what I might need to do to get it working?
