Monitored Notification Page

The hypervisor collects monitored notifications in monitor overlay pages that can be created or deleted only from a parent partition. The parent partition creates a monitor-page port in the recipient and specifies the guest physical address (GPA) of the recipient's associated monitor page. The parent subsequently creates a connection to that monitor page port in the originator and specifies the GPA of the originator's associated monitor page. While each of these two GPAs is specific to a partition, the underlying physical page is a common page that is managed by the hypervisor. Changes to the page are accessible from both partitions as well as the hypervisor.
