When saving a domain, its htab must be copied, real page numbers replaced with
then written to disk. To copy the htab, I've tried for many hours to add a
#define XEN_DOMCTL_gethtab 29, using code and structures similar to
This new command makes it through do_xen_hypercall(), however, always get
On the Xen side, hcall_xen() I print all the command numbers for do_domctl ops,
new command never arrives. Of course, have added a 'case XEN_DOMCTL_gethtab' in
and also printk before ENOSYS, but this code is never run.
1) Is this a reasonable approach to copying the htab?
2) Any clues?
