The logic still exists in xen/drivers/passthrough/io.c, though documentation suggests MSI-INTx translation is only implemented for HVM guests. Based on the disabling of MSI-INTx by default, it seems safe to assume that MSI translation is only supported under qemu-xen-traditional, and only for HVM guests. Is this correct? I don't see any mention of this on this wiki page: http://wiki.xen.org/wiki/QEMU_Upstream #Missing_feature_from_the_good_old_qemu-dm
