Hi,
Do you mean Xen virtual machine?
Is there detailed tutorial for customizing a disk image,
I find the related document on gem5 wiki is very sketchy. Thanks.

I think the disk image can be created using virtual machine environment.
Anyways, from the printed rip value, you can try to figure out which
instruction is causing the segmentation fault and why. Looking through the
trace of executed instructions should help.
