(Doc ID 1065607.1)

Last updated on DECEMBER 20, 2010

Applies to:

Oracle Server - Enterprise Edition - Version: 11.2.0.1.0 to 11.2.0.1.0 - Release: 11.2 to 11.2
Generic Linux

Symptoms

In 11.2.0.1.0, when installing or cloning Grid Infrastructure (Clusterware), root.sh installs the ASM Cluster File System (ACFS). When installing ACFS in a domU running a xen/OVM kernel, the base Linux driver installation routines may overwrite grub.conf with an incorrect version. When this happens, the following error may occur:

the VM fails to boot with the following error:

# xm create vm.cfg
Using config file "./vm.cfg".
Error: Boot loader didn't return any data!

This problem has been observed on OEL5/RHEL5 Update 3 and OEL5/RHEL5 Update4.

Changes

This can happen during 11.2.0.1.0 Grid Infrastructure (Clusterware) installation or cloning operation.
