Question about upstream qemu and seabios on xen git

Question about upstream qemu and seabios on xen git

[Fabio Fantoni]

I continue to do periodical test of xen-unstable with latest stable 
and/or unstable upstream qemu and seabios version.
Today for example I start to test qemu 1.5.1, no bugs found for now.

I think is better to maintain updated upstream qemu and seabios also on 
xen gits while xen is not "code freeze".
For xen develop/testing xen gits are mainly used, but on production the 
distributions will use latest stable qemu version (for example on debian 
experimental is releasing xen 4.3 and qemu is already 1.5.1 on debian 
unstable but xen 4.3 was freezed with qemu 1.3 and mainly tested with it).
Therefore should be best to have all components early updated as possible.

An example of a critical bug found testing latest qemu version (hvm 
domUs with qemu 1.4 was unable to boot with stdvga) found using more 
updated qemu that was already on debian repository but not on git used 
by xen:

Thanks for any reply

I'm not entirely sure what you are suggesting but it sounds like you
simply want to pull upstream qemu and seabios for testing purposes? If
so then I think there is nothing wrong with pulling these directly from
their respective upstreams, so long as you clearly indicate this (and
the version being tested) in any bug reports.

Thanks for reply.
To test latest upstream qemu and seabios version I already use debian 
packages (latest stable version) or I change Config.mk of xen to point 
upstream gits instead (for unstable version).
Based of my example of some months ago its seem that xen 
developers/testers are using only xen git except rare cases, so I mean 
that xen gits of qemu and seabios should pull from upstream gits most 
frequently.

I think you are right, in fact I intend to update the QEMU tree for
xen-unstable very soon, basing it on the latest release, 1.5.2.

Thanks.
I have a question also about enabling spice on xen's qemu compile.
Last year I propose to add it with 3 method, all rejected.
Newer distribution version have all spice prerequisite packages, so this 
option is quite worth for me.
libxl has already spice basic support and I started to post some patch 
to make it full features.
