| 8. A method of processing interrupts for a virtualized computing system, the virtualized computing system comprising a virtual
machine monitor and at least one guest operating system, the method comprising:
receiving an end-of-interrupt command from a guest operating system;
determining that the end-of-interrupt command does not correspond to a highest priority interrupt flagged as being in-service;
recording information identifying the interrupt corresponding to the received end-of-interrupt command; and
processing the end-of-interrupt command after an end-of-interrupt command for the highest priority interrupt flagged as being
in-service is received.
