   An update that has two recommended fixes can now be
   installed.

Description:

   This update for xen fixes the following issues:

   - Booting Fedora31 VM on SLES-15-SP1 Xen Domain 0. (bsc#1162040) This
     solve a Grub2ConfigFile issue with a wrong handling of next and saved
     entries.
   - Update to Xen 4.12.2 including upstream fixes (bsc#1027519) This update
     will also clear stubs.addr and stubs.mfn in order to allocate a new stub
     page when needed, whether the CPU gets parked or removed. Event channels
     are the basic primitive provided by Xen for event notifications. This
     fix will also improve the event channel handling.
