RE: [Xen-users] crashes windows 2008 server in hvm

["James Harper" <james.harper@xxxxxxxxxxxxxxxx>]

I have found and fixed a problem and am uploading a fixed version.

This fixed version though contains a bunch of changes to the xenbus code
which isn't well tested, but appears to work. Please only use it if you
are using Vista/2008, which appear to always run with PAE enabled if
it's available, and therefore uses 64 bit addressing. Despite an earlier
email, shutdownmon does actually appear to work under this version.

The exe is called "Xen PV Drivers 0.9.12-pre10-dont-use.exe". I put the
-dont-use bit there to discourage anyone from trying it just because
it's there :)

Please let me know if that does or doesn't fix your problems. Please
test in a test environment first too if at all possible!

Thanks

James
