Hi,

Given that libvirt is also a general purpose hypervisor, more like VBox
or VMWare Workstation, which is used occasionally.

Should ksm services also be provided as a socket so that they are
activated on-demand? libvirt is already doing something similar.

Given that KSM depends on cgroups, especially memcg, should this be
ported to using systemd's timer/socket feature ?

Just that I didn't like the sleep call.
