Each source is associated with an Event State Buffer (ESB) with a even/odd pair of pages which provides commands to manage the source: to trigger, to EOI, to turn off the source for instance. The custom VM fault handler will deduce the guest IRQ number from the offset of the fault, and the ESB page of the associated XIVE interrupt will be inserted into the VMA using the internal structure caching information on the interrupts.
