You're misreading the meaning of the word "data" in this context.  In this
context "data" simply means memory page contents, not "program data
structures" as in program variable contents (my_name = "Stan").  If you
understood the previous paragraph in the doc, this should have been crystal

VMs run as processes on top of the host Linux kernel+KVM.  Thus, they are no
different from a memory management standpoint than any other process.  KSM
wasn't specifically designed for memory consolidation of the contents of
virtual machines.  Again, they are regular Linux processes.  Thus, KSM works
on non VM processes exactly the same way.

Repeat after me:  "A process is a process is a process."
