This was due to the fact that:

 * The test system thought that qemu-upstream-4.2-testing.git
   should exist because it was constructing the qemu branch name
   programmatically and overriding xen.hg's idea of which qemu version
   to use.

 * qemu-upstream-4.2-testing.git did not actually exist.
   This was because our release checklist didn't say to branch
   qemu-upstream.unstable.git.
   This was because we hadn't actually made a decision whether to
   branch qemu-xen-upstream for 4.2.

Also I discovered that:

 * xen-4.2-testing.hg's Config.mk referred to qemu-xen-unstable.git.
   This was because our release checklist didn't say to change this
   (and Keir didn't do so when making the various tags).

I have:

 * Checked with Ian C and Stefano and agreed that we want to branch
   xenbits's qemu-upstream-unstable.git.

 * Actually made the new trees and updated the checklist.

 * Pushed a change to xen-4.2-testing.hg to update Config.mk.
   (see below).

 * Poked the test system to start a retest of 4.2.

I'm afraid that we should still refrain from pushing substative
changes to xen-4.2-unstable.hg.

Sorry for the inconvenience.  The root causes are that (a) we have
accumulated 18 months' worth of bitrot in our process (b) we didn't
remember to update the releasing/branching checklist when inventing
new qemu trees.

Ian.

Config.mk: Change qemu references to 4.2-testing trees

QEMU_REMOTE and QEMU_UPSTREAM_URL need to refer to
git://xenbits.xen.org/qemu-{xen,upstream}-4.2-testing.git
(or the corresponding http versions), not -unstable.git.
