Hi, Can someone interpret how HVM guest communicate with domain0, as i know, H VM can not use event channel directly, is the platform-pci offer a way to solve this? Please try to explain concretely, for example : 1.how does HVM send a event to domain0, how does domain0 catch this event, and assoicate it with a handler 2.the opposite direction, how does domain0 send event to HVM guest? Does it do something through the platform-pci? what the platform-pci does first? Does it create a virtual pci device? Then does domain0 send event to this pci device to fire a interupt ? How does it do this? Finally, I just need to deal with this interupt? Something like that, i hope someone can give a detailed depiction that can make me draw a flow chart. Thanks.
