Hello, on Oct 02, Debian-security released 8 fixes for qemu-2.8. In total there are 46 patches since the release of qemu-2.8 on Jul 21. As shown, in the fpaste, I applied these 46 to the upstream xen-4.9 tarball while trying to package in Stretch. All applied cleanly. As a source of qemu fixes xen-4.9, I've looked here: you can see there is only 1 fix since the release of xen-4.9.0 (Jun 27). Any harm in using the debian-delta for qemu fixes? Should these be auto-tested by xenproject?

How critical can it be? It's not very critical, if you are using a released version of Xen. In particular, if it builds, you're unlikely to go very far wrong. NB though that (as you suggest from "built together") the Xen control libraries that qemu uses 1. do not have a stable ABI until recently (sorry) 2. do not have a stable interface to the hypervisor. So unless you are using the very latest bits, you must rebuild when you use a different Xen version. Additionally, the qemu configure script works by determining the Xen version (rather than by looking for individual features) and keying everything off that. So if you are using xen-unstable, you will find that some qemu versions don't build.
