I have migrated the domain pages to a new domain, and am trying to get
it to resume after migration. I am currently crashing sometime shortly
after resumption, and I have instrumented Xen to dump some info about
the state of the domain.

Since I am reading all info from inside the old domain 'by hand', this
is probably a case of some CPU state I have not managed to get across. 

I am quite sure the crash is due to a wrong stack page being pointed to,
but since my recovery code is running in ring1 in a __cli() context, I
suppose the ring3 stack cannot be to blame.
