Re: [libvirt] [PATCH v2 3/5] event: introduce new event for cputune

This new event will use typedParameters to expose what has been actually updated and the reason is that we can in the future extend the cputune. With typedParameters we don't have to worry about creating some sort of v2 of cputune event if there will be new features implemented for cputune.
