Dear Team, When reading the slide of xVM I have a question about the xVM architecture, as dom0 is a control domain, it will include a back-end layer for handle HW request from domU3, but if domU1 is set as PV, it will also has a back-end layer. My question is what''s the relation ship between this two back-end layer and as there is an arrow between domU2 & domU1, does it mean that the domU1 will also work as control domain to handle HW request? Thanks. Best Regards /Richard Liu
