Fabio,

Is that something you would be comfortable taking a look at? I fear
that a lot of us are busy with some of the hypervisor development and
this is kind of on the end of the plate - which means we would probably
get to it but not right away :-(

From qemu 1.3 I kept testing the upstream qemu as far as I could, to find and report any regressions with xen.
Unfortunately I did not have enough time and in some cases the knowledge to fix and/or improve some things to try to ensure a good integration, use of the main new qemu features, and exemptions from criticism regressions with xen before of the new qemu stable versions release.
An important first step, perhaps the most important would be to keep the tested with qemu upstream xen during the development of each version (http://git.qemu.org/?p=qemu.git;a=shortlog;h=refs/heads/master) in order to immediately identify any regression with xen and resolve as soon as possible or at least report it on qemu-devel.
I gave a quick look at the git osstest to eventually try to use it on a test server and run necessary automated tests for the nights but I did not understand enough and I have almost no knowledge of perl, and perhaps even more my very bad english...

My first doubts about osstest for example:
must to have 2 test systems (osstest controller and test xen host) on a network that is without others dhcp and dns servers outside of the controller but connected to the internet or am I wrong?

There is a method to easy and fast have working dns/dhcp/tftp enough to osstest?

Thanks for any reply and sorry for my bad english.
