______________________________________________________________________________

   An update that solves one vulnerability and has four fixes
   is now available.

Description:

   This update for xen fixes the following issues:

   Security issue fixed:

   - CVE-2021-28689: Fixed some x86 speculative vulnerabilities with bare
     (non-shim) 32-bit PV guests (XSA-370) (bsc#1185104)

   - Make sure xencommons is in a format as expected by fillup. (bsc#1185682)

     Each comment needs to be followed by an enabled key. Otherwise fillup
   will remove manually enabled key=value pairs, along with everything that
   looks like a stale comment, during next pkg update

   - A recent systemd update caused a regression in xenstored.service systemd
     now fails to track units that use systemd-notify (bsc#1183790)
   - Added a delay between the call to systemd-notify and the final exit
     of the wrapper script (bsc#1185021, bsc#1185196)
