Hi,
The linux headers do include the MADV_MERGEABLE settings, and the libc
is the debian one which happened to work fine earlier in this regard.
Anyway I still added the flags just to make sure, and nothing more happens.
Cheers,

Hi,
I'm running a 2.6.32.7 kernel with KSM enabled (CONFIG_KSM=y), with
qemu-kvm 0.12.2 that has support for KSM (exec.c checks for
MADV_MERGEABLE)..
So I have KSM running, /sys/kernel/mm/ksm/run is at 1, and after a
few hours running a dozen of VMs, many of them running the same
OS/base image, I see no page being shared, KSM seems inactive.
Values are pretty much to their default value, and it seems KSM is
simply not working.. I see ksmd in the process list though, but here
are the sysfs values reported:
==> /sys/kernel/mm/ksm/full_scans <==
0
==> /sys/kernel/mm/ksm/max_kernel_pages <==
1027257
==> /sys/kernel/mm/ksm/pages_shared <==
0
==> /sys/kernel/mm/ksm/pages_sharing <==
0
==> /sys/kernel/mm/ksm/pages_to_scan <==
100
==> /sys/kernel/mm/ksm/pages_unshared <==
0
==> /sys/kernel/mm/ksm/pages_volatile <==
0
==> /sys/kernel/mm/ksm/run <==
1
==> /sys/kernel/mm/ksm/sleep_millisecs <==
20
Any clues?
Cheers,
Gilou
