Package: qemu-kvm
Version: 0.12.5+dfsg-2
Severity: wishlist
It is very difficult to find how enabling KSM with qemu-kvm. When googling, I
find that Debian libc, qemu-kvm and kernel should have all what is needed for
ksm to work and I do not understand why /sys/kernel/mm/ksm/pages_sharing was
always to 0.
It is only today that I found that I have to
echo 1 > /sys/kernel/mm/ksm/run
in order to have KSM working (I also adjust sleep_millisecs to 2000)
I think the info (or a pointer to better documentation) would be welcomed
in /usr/share/doc/qemu-kvm/README.Debian.gz
Regards,
Vincent
