Fence Device - Oracle VM

 Hello all;

I have 2 virtual machine guest running on Oracle VM. The VMs OS is Oracle Linux 5.9. I need to implement the "High Availability" (Cluster Suite) features on the Linux OS. My problem is the fence device. Which fence device I should use to ensure correct fence behavior.

Thanks for advance.

My cluster.conf

<?xml version="1.0"?>

<cluster alias="oracluster" config_version="6" name="oracluster">

        <fence_daemon post_fail_delay="0" post_join_delay="20"/>

        <clusternodes>

                <clusternode name="orasrv1" nodeid="1" votes="1">

                        <fence>

                                <method name="1">

                                        <device domain="orasrv1" name="xvm"/>

                                </method>

                        </fence>

                </clusternode>

                <clusternode name="orasrv2" nodeid="2" votes="1">

                        <fence>

                                <method name="1">

                                        <device domain="orasrv2" nodename="xvm"/>
