The changset 21229 breaks Xen 4.0.1 tree on 32bit environment. Starting a guest VM will throw out an error as "Error: (38, 'Function not implemented')". Apparently, the hypercall to mem_sharing_op is missing for 32bit environment due to 21229. The following small patch can fix this issue.
Thanks,

This will be the unconditional xc.dom_set_memshr() call in xend's image.py.
Should be wrapped in try-except.

Should be fixed by xen-unstable:21751 and xen-4.0-testing:21258.
