No, we don't.  (In fact I think it's a bug that it doesn't show the
whole series of 6 commits.)

As Stefano says, it's a 32-bit Windows XP install.  It's on a 32-bit
hypervisor.  The full details can be found from various links here:

The key part this this, which is from the link at the top of the
column with the regression (whose cell is highlighted in pink):

 
http://www.chiark.greenend.org.uk/~xensrcts/logs/16779/test-i386-i386-xl-qemuu-winxpsp3/info.html

There you can find various logfiles, but crucially also the domain
configuration.

I'm afraid the ISO used for the installation is not available for
obvious reasons.

Ian.
