grub2 2.02~beta2-16 finishes off Xen host/guest integration. GRUB has
had most of this for a while, but the packaging work to make it possible
to install grub-xen-host in the host, grub-xen in the guest, and then
automatically boot GRUB in the guest wasn't present.
I know this is a bit more than your standard unblock request, and indeed
we're still waiting for this to pass through NEW. But we're
anticipating this being *really* useful for administrators of Xen
hosting setups - it beats the messes that were PV-GRUB Legacy and
PyGrub, or even keeping track of kernel versions by hand - and it would
be fantastic to have this in jessie.
Here's a tidied-up version of the relevant git diff.

+Description: GRand Unified Bootloader, version 2 (Xen host version)
+ GRUB is a portable, powerful bootloader. This version of GRUB is based on a
+ cleaner design than its predecessors, and provides the following new features:
+ .
+ - Scripting in grub.cfg using BASH-like syntax.
+ - Support for modern partition maps such as GPT.
+ - Modular generation of grub.cfg via update-grub. Packages providing GRUB
+ add-ons can plug in their own script rules and trigger updates by invoking
+ update-grub.
+ .
+ This package arranges for GRUB binary images which can be used to boot a Xen
+ guest (i.e. PV-GRUB) to be present in the control domain filesystem.

+Subject: grub-install: Install PV Xen binaries into the upstream specified
+ path
+
+Upstream have defined a specification for where guests ought to place their
+xenpv grub binaries in order to facilitate chainloading from a stage 1 grub
+loaded from dom0.
+
+http://xenbits.xen.org/docs/unstable-staging/misc/x86-xenpv-bootloader.html
+
+The spec calls for installation into /boot/xen/pvboot-i386.elf or
+/boot/xen/pvboot-x86_64.elf.
