           Summary: Xen 3.1: can't run PV Fedora Core 1 Images any more
           Product: Xen
           Version: unspecified
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P2
         Component: Hypervisor
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: nick@xxxxxxxxxxxxxx

I've just built Xen 3.1 x86 32 bit with PAE from source. 

Both the dom0 and PV domU are running which I made by using
"make mkpatches" and applying the patch produced to a vanilla
as donwloaded from kernel.org.  There was one reject which I
ascertained was a patch that had already been applied to the Xen

Xen 3.1 runs most of my domUs just fine, windows etc, but it doesn't
run a Fedora Core 1 image.  It hangs at 100% cpu usage just after
"Freeing kernel memory".

If I mount the FC1 image on dom0 and chroot into it I get

  # chroot . /bin/bash
  Segmentation fault

I've put a small ext2 filing system here (built from a virgin FC1
image) which demonstrates the problem


Mounting it and chrooting from dom0 under Xen 3.1 gives the SEGV.
Doing the same from Xen 3.0.3 , Xen 3.0.4 and Debian testing works
