[Xen-devel] [PATCH RFC OSSTEST v1 12/12] make-flight: Use older Debian for host and guest OS with older Xen

[Ian Campbell <ian.campbell@xxxxxxxxxx>]

Sometimes when updating osstest to use a newer version of Debian as a
baseline we find that the new compiler or other tools pickup latent
errors in older code bases for which the fixes are invasive or
otherwise inappropriate for a stable branch.

This is the case with Debian Jessie and Xen 4.3 and earlier, so
restrict those branches to keep using Wheezy.

This only applies to xen-X.Y-testing branches and
qemu-upstream-X.Y-testing branches since other branch all use
xen-unstable as their Xen.
