Hello, it seems to me that after upgrading to some 2.6.32.x release, KSM stopped working for me. I'm not exactly sure which update did this, but enabling KSM doesn't seem to do anything, ksmd process just sleeps and doesn't merge any memory. Early 2.6.32 versions worked correctly for me, now I'm using 2.6.32.7 and qemu-kvm-0.12.2. I'm enabling it using: echo 262144 > /sys/kernel/mm/ksm/pages_to_scan echo 100 > /sys/kernel/mm/ksm/sleep_millisecs echo 1 > /sys/kernel/mm/ksm/run Is there anything else I could check? Thanks a lot for any hints with best regards nik -- ------------------------------------- Ing.
