Nested KVM issue
For myself KSM is unpredictable feature. The problem is Compute, just this node
does "copy on write" , so only Compute.
My concern exactly is where would it lead to worse or better Guest behavior ?
I am not expecting complete fix. I would track via top/htop and dmesg via Cron on 1-2 hr
period.

[RFC PATCH v6 00/92] VM introspection
The KVM introspection subsystem provides a facility for applications running
on the host or in a separate VM, to control the execution of other VM-s
(pause, resume, shutdown), query the state of the vCPUs (GPRs, MSRs etc.),
alter the page access bits in the shadow page tables (only for the hardware
backed ones, eg. Intel's EPT) and receive notifications when events of
interest have taken place
