My bisection shows the following commit is the culprit.


9ff6dbfa7576cc1c5d6f9a3c59c69a8503e36f11 is the first bad commit

    tools/dombuilder: Prevent failures of xc_dom_gnttab_init()

    Recent changes in grant table configuration have caused calls to
    xc_dom_gnttab_init() to fail if not proceeded with a call to
    xc_domain_set_gnttab_limits().  This is backwards from the point of view of
    3rd party dombuilder users.

    Add max_{grant,maptrack}_frames parameters to struct xc_dom_image, and 
require
    them to be set by callers using xc_dom_gnttab_init().  Libxl, which uses
    xc_dom_gnttab_init() itself is updated appropriately.
