   The number of people who have it working would tend to suggest that
there's either some problem with the specific packages that you're
using, or there's a problem with your hardware, or there's something
that you haven't understood. From here, it's hard to tell which at the
moment -- it could even be some combination of the three.

   This looks OK. You have the VMX flag.

   Seems to be OK.

   It's possible there's a problem with your hardware (some BIOSes
turn VMX off), but it's hard to tell with what you've posted here.
Please give us the output of "xm info", the domain config file you're
using, and the contents of the relevant /var/log/xen/qemu-dm.<n>.log
file from starting your Windows VM (i.e. start then VM, then look for
the qemu-dm log file with the most recent datestamp).

   Debian and Ubuntu both have Xen packages. I had the Debian ones
working (briefly) last night.

   I would suggest trying to build Xen from source, as it's what
worked for me. You can get the source by installing mercurial, and
using:

$ mkdir xen && cd xen
$ hg init
$ hg pull http://xenbits.xensource.com/xen-3.0.4-testing.hg
$ hg update

then tar up the whole directory, copy it to the system you're trying
to set up, and build it using the instructions included. You will also
need a 2.6.16.33 kernel tarball, python, the python development
package(s), and a couple of other development packages (but you will
be told about those if they're missing when you try to build it).

   If you do build from source, make sure that you remove all
Xen-related packages from your install first, otherwise you could end
up with the wrong version of the device model, and nothing will work.

   Hugo.
