I think we need this to include a clear indication that the release is NOT a
specific upstream changeset, but is in fact our own variant on that, complete
with other patches.  So perhaps

xen_changeset          : 15042.el5

makes sense.

Requesting for 5.2.

Comment 5 Stephen Tweedie 2007-07-06 11:43:13 UTC
Also, what do we do about the fact that userland is based off multiple different
releases (one for python, another for hvm environment); and that the kernel and
hypervisor are based off different csets, too?

Sounds like "unavailable" is actually the most accurate response to a user
asking what our Xen version is.  :)

Comment 6 Daniel Berrange 2007-07-06 13:30:38 UTC
Personally I recommend against including any form of changeset information,
simply because there is no meaningful changeset we can provide. The HV may be
based off 3.1, but its got a number of patches added. The userspace bears no
resemblance to any upstream changeset. Nor does the kernel. We should not try to
pretend that we have any correspondance to a changeset because it'll just
encourage people to make meaningless comparisons between functionality/bugs in
upstream vs our tree.
