This needs dom0 kernel changes and does not solve the general sharing problem (among multiple HVM domains, or among HVM domains and PV domains other than dom0). Could you somehow track which guest is most likely to handle the interrupt, deliver to it first, and then detect the immediate re-interrupt if it EOIs without handling? Plus have a timeout if it does not EOI in reasonable time? -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
