Hi there!
I'm trying to understand kvm performance bottleneck and I was hoping to
get sharing statistics form ksm. Was not able to locate it so far, the
below mentioned /sys entry is missing, while ksm module is loaded.
I'm using latest from rhel 5 x64: 2.6.18-194.el5, kmod-kvm-83-164.el5 and

If the slowdown is indeed due to I/O, LVM (with cache=off) should
eliminate it completely.
As promised I have installed LVM: The difference is remarkable.
My test case (running 8 vhosts in parallel, each building a Linux
kernel) just works. There is no
