Installing Vista 32bit crashes xen

I am trying ti install vista 32 bit in some xenU-domain, but after the reboot following Service Pack 1 the virtual machine vanishes.

This bug seems to be reproducable, I already tried to install vista yesterday and had the same crash. Even after booting the incomplete installation again, it crashes.

Now, I found the following in xend.log

[2009-06-13 20:38:23 4495] WARNING (XendDomainInfo:1283) Domain has crashed: name=vista32 id=46.

and when typing “xm dmesg” I see (I paste here just the relevant lines):

Now it seems, that something very similar happend already to someone else and a fix might be already available:
[Xen-users] svm.c:83:d917 Bad instruction length 0 - Xen Source]([Xen-users] svm.c:83:d917 Bad instruction length 0 - Xen Source)

Any idea how I can get rid of this bug?
Thanks

I finally upgraded to 11.1 with Xen 3.3.1 and the bug is vanished.
