Hi,
I tried to use crash (http://people.redhat.com/~anderson/) with
x86_32 xen domain0 image, which is extracted from whole-machine dump
image made by kexec/kdump.
'kmem -i' cause some error, but other almost all commands I tried seem
to work well.
This may be some helps for xen development and troubleshooting.
regards,
