[Linux-cluster] Failed to start a "virtual machine " service on RHCS in CentOS 6



Hi, All:

I have two physical machines as KVM hosts (clusterA.RHCS and clusterB.RHCS) , an iscsi target set into GFS. 
All I want is a HA Cluster which could migrate all the virtual machines on a node to another when the first node failed into some error status.

So I created a cluster "cluster" using RHCS ,added the two hosts into the cluster . created a fence device .
for every virtual machine on clusterA , create a service ,added a resouce which type is "virtual machine" , and set it's properties.

But when I start the service ,I got these errors in /var/log/message :

[root clusterA ~]# tail -f /var/log/messages
Nov 24 16:19:29 clusterA libvirtd: Could not find keytab file: /etc/libvirt/krb5.tab: Permission denied
Nov 24 16:19:30 clusterA modclusterd: startup succeeded

Nov 24 16:19:56 clusterA rgmanager[2198]: Stopping service vm:wuguang-xp
Nov 24 16:19:56 clusterA rgmanager[6850]: Using /etc/libvirt/qemu/wuguang-xp.xml instead of searching /etc/libvirt/qemu
Nov 24 16:19:56 clusterA rgmanager[6906]: xend/libvirtd is dead; cannot stop wuguang-xp
Nov 24 16:19:56 clusterA rgmanager[2198]: stop on vm "wuguang-xp" returned 1 (generic error)
Nov 24 16:19:56 clusterA rgmanager[2198]: Marking vm:wuguang-xp as 'disabled', but some resources may still be allocated!
Nov 24 16:19:56 clusterA rgmanager[2198]: Service vm:wuguang-xp is disabled


But I set the libvirt tcp authority to "none" , here is my libvirtd.conf:


listen_tls = 0


listen_tcp = 1


tcp_port = "16509"
 
auth_tcp = "none"



my cluster.conf is :

<?xml version="1.0"?>
<cluster config_version="83" name="cluster">
<fence_daemon clean_start="0" post_fail_delay="0" post_join_delay="3"/>
<clusternodes>

</clusternode>
<clusternode name="clusterB.RHCS" nodeid="2" votes="1">

</clusternodes>

</service>
<vm autostart="1" domain="FD" exclusive="0" migrate="live" name="wuguang-xp" path="/etc/libvirt/qemu" recovery="relocate" xmlfile="/etc/libvirt/qemu/wuguang-xp.xml"/>
</rm>
</cluster>

What's wrong with my configuration of RHCS or libvirt?
Thanks in advance
