libvirt users - Nov 2011 - 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 at 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 16:19:56 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>

<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
