Subject: [PATCH] fix Grub2 with SUSE Xen package install
|
||
|
|
|
||
|
|
References: bnc#774666
|
||
|
|
Patch-Mainline: no
|
||
|
|
|
||
|
|
This fixes Grub2 does not offer a Xen entry after installing hypervisor
|
||
|
|
and tools, which is caused by install sequence of xen-kernel and xen is
|
||
|
|
unpredictable.
|
||
|
|
|
||
|
|
By judging the system is dom0 with xen kernel installed, the xen_list
|
||
|
|
will be set to /boot/xen.gz if it's empty. Because the xen kernel would
|
||
|
|
trigger the config updated prior to the xen package installation.
