Hi Gianluca, KSM comes with qemu-kvm, so no point of looking for it as an rpm: # rpm -ql qemu-kvm | grep ksm /etc/ksmtuned.conf /etc/rc.d/init.d/ksm /etc/rc.d/init.d/ksmtuned /etc/sysconfig/ksm /usr/sbin/ksmtuned As for the actual issue, which cluster policy are you using now? See the attached to illustrate what I'm referring to.
