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:

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"?>

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