Let me clarify this, here is the table: 1. upstream qemu + guest kernel MSI support --- doesn't work 2. upstream qemu + guest kernel no MSI support --- work 3. mst qemu git tree + guest kernel MSI support - vhost --- work 4. mst qemu git tree + guest kernel MSI support + vhost -- doesn't work I hope it's clear. thanks Shirley -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
