-/** Grant table version to try setting
- *
- * Using version 1 grant tables limits guests to using 16TB of
- * grantable RAM, and prevents the use of subpage grants.  Some
- * versions of the Xen hypervisor refuse to allow the grant table
- * version to be set after the first grant references have been
- * created, so the loaded operating system may be stuck with whatever
- * choice we make here.  We therefore currently use version 2 grant
- * tables, since they give the most flexibility to the loaded OS.
- *
- * Current versions (7.2.0) of the Windows PV drivers have no support
- * for version 2 grant tables, and will merrily create version 1
- * entries in what the hypervisor believes to be a version 2 table.
- * This causes some confusion.
- *
- * Avoid this problem by attempting to use version 1 tables, since
- * otherwise we may render Windows unable to boot.
- *
- * Play nicely with other potential bootloaders by accepting either
- * version 1 or version 2 grant tables (if we are unable to set our
- * requested version).
