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-...@lists.xensource.com ReportedBy: ni...@craig-wood.com

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

Both the dom0 and PV domU are running 2.6.18.8 which I made by using "make mkpatches" and applying the patch produced to a vanilla 2.6.18.8 as donwloaded from kernel.org. There was one reject which I ascertained was a patch that had already been applied to the Xen kernel.

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 fine.
