  This patch series is intended to add some selected information
to the kvm tracepoints to make it easier to gather insights about
running nested guests.

This patch series was developed together with a new x86 performance analysis tool
that I developed recently (https://gitlab.com/maximlevitsky/kvmon)
which aims to be a better kvm_stat, and allows you at glance
to see what is happening in a VM, including nesting.

Best regards,
	Maxim Levitsky
