In one of the previous version of the patchset there was a suggestion to implement the new vm_event transport using IOREQ, but it was dropped . https://lists.xenproject.org/archives/html/xen-devel/2019-04/msg00173.html Also, unless there isn't a proper way allocate the necessary pages, I wouldn't introduce a HVM-only limitation because, other than the HVM param used to keep track of the ring pfn, the vm_event mechanism is quite generic.
