There is absolutely no correlation, none whatsoever, between memory
load and the amount of KVM the system is using. Zero. Zip. Nada.
Trying to tie the two together is a complete waste of time. KVM
utilization should be self regulating, but if you try to do something
'special' in low memory situations you will screw yourself badly ...
you will make a system that is already inefficient from the load even
more inefficient and less able to recover.
