In my case it was just a wrong domid. Now I use 'xl domid domU' and
xenpaging does something. It seems paging out and in works still to some
degree.  But it still/again needs lots of testing and fixing.

I get errors like this, and xl dmesg has also errors:

...

xc: detail: Need to resume 200 pages to reach 131328 target_tot_pages
