From 2e13fbe42d7aed77d1b1c62b342d080c2510af0e Mon Sep 17 00:00:00 2001 From: Fan Zhang Date: Thu, 12 Feb 2015 18:02:16 +0100 Subject: [PATCH] s390x/ipl: make s390x ipl device aware of migration We have to migrate the reipl parameters, so a reboot on the migrated machine will behave just like on the origin. Otherwise, the reipl parameters configured by the guest would be lost.
