Subject: [PATCH] fix menu in xen host server
References: bnc#771689, bnc#757895
Patch-Mainline: no
When system is configred as "Xen Virtual Machines Host Server", the
grub2 menu is not well organized. We could see some issues on it.
- Many duplicated xen entries generated by links to xen hypervisor
- Non bootable kernel entries trying to boot xen kernel natively
- The -dbg xen hypervisor takes precedence over release version
This patch fixes above three issues.
