   An update that contains security fixes can now be installed.

Description:

   This update for xen fixes the following issues:

   - A recent systemd update caused a regression in 'xenstored.service'
     systemd now fails to track units that use systemd-notify. (bsc#1183790)
   - Add a fix to delay between the call to 'systemd-notify' and the final
     exit of the wrapper script. (bsc#1185021, bsc#1185196)
   - Run xenstored in a separeately, which will make processing of large
