Why not putting this into sysfs ?

Because sysfs is "one value per file".

I see two options:

a) if it's really kvm-specific (and no chance of using the same interface for other hypervisors), we could put it under the kvm device (/sys/class/misc/kvm).

Again, that is NOT what sysfs is for.

b) have a generic VMM stats interface that theroretically could work with any hypervisor.

What other hypervisor matters?
