Enable KSM

Mun

Anyone know how to enable KSM on debian, without KVM installed. I run multiple TF2 instances and would like the benefit of more memory.

Thanks.

Edit:

I have already done echo 1 > /sys/kernel/mm/ksm/run

Still nothing though.

@Mun It only kicks in under certain conditions regardless of that command.

KSM doesn't work like that.

Memory that's "merge-able" must be marked as such. KSM then scans your memory looking for said memory and then merges when it can

There was a kernel patch called 'uksm' that provided this but it seems the project doesn't exist on code.google.com anymore

Damn, was hoping I could do it. Guess I need to go ESXI

@Mun Try using up more than half of your RAM with KVM vms and then enable KSM. See what that does and get back to us ;-)

Proxmox is easier and doesn't chomp away support for things.

ESXI doesn't have a real OS for the host side so it sucks.
