As far as i can see, items 2 and 3 of https://lkml.org/lkml/2012/11/12/588 Have not been addressed. https://lkml.org/lkml/2012/11/20/653 contains discussions on those items. 2) Format of the interface for other architectures (you can choose a different KVM supported architecture and write an example). It was your choice to choose an I/O port, which is x86 specific. 3) Clear/documented management interface for the feature. Note 3 is for management, not the guest<->host interface. > On Wed, Dec 12, 2012 at 02:13:43PM +0800, Hu Tao wrote: > > This series implements a new interface, kvm pv event, to notify host when > > some events happen in guest.
