Hi!
I have been trying to get a KVM guest running as a clustered service
(two node cluster with GFS2 shared images), in order to restart the
guest on the alive cluster node, in case the other node crashes. The
problem is that I can't get the VM service managed by the cluster
daemons (manually start/stop/live migrate my VM guest works fine).
This is how my "cluster.conf" file looks like:
<?xml version="1.0"?>
<cluster config_version="16" name="KVMCluster">
<fence_daemon post_fail_delay="0" post_join_delay="10"/>
<clusternodes>
<clusternode name="nodeAint" nodeid="1" votes="1">
<multicast addr="239.0.01" interface="eth2"/>
<fence>
<method name="single">
<device name="nodeA_ilo"/>
</method>
</fence>
</clusternode>
<clusternode name="nodeBint" nodeid="2" votes="1">
<multicast addr="239.0.0.1" interface="eth2"/>
<fence>
<method name="single">
<device name="nodeB_ilo"/>
</method>
</fence>
</clusternode>
</clusternodes>
<quorumd interval="1" label="QuoDisk" tko="10" votes="1"/>
<cman expected_votes="3" two_node="0">
<multicast addr="239.0.0.1"/>
</cman>
<fencedevices>
<fencedevice agent="fence_ilo" hostname="nodeAcn" login="hp"
name="nodeA_ilo" passwd="hpinvent"/>
<fencedevice agent="fence_ilo" hostname="nodeBcn" login="hp"
name="nodeB_ilo" passwd="hpinvent"/>
</fencedevices>
<rm log_level="7">
<failoverdomains>
<failoverdomain name="FD1" ordered="0" restricted="0">
<failoverdomainnode name="nodeAint" priority="1"/>
<failoverdomainnode name="nodeBint" priority="1"/>
</failoverdomain>
</failoverdomains>
<service autostart="1" exclusive="0" domain="FD1" name="guest00_service"
recovery="relocate">
<vm domain="FD1" autostart="1" migrate="live" use_virsh="1"
hypervisor="qemu" name="guest00" hypervisor_uri="qemu+ssh:///system"
path="/etc/libvirt/qemu/guest00.xml">
</vm>
</service>
<resources/>
</rm>
<dlm plock_ownership="1" plock_rate_limit="0"/>
<gfs_controld plock_rate_limit="0"/>
</cluster>
And these are the errors I'm getting at syslog:

I have checked the status of the libvirtd daemon, and it's running fine:
[r...@nodeb ~]# service libvirtd status
libvirtd (pid 5352) is running...
And all VM guests management using "virsh" is also running fine.
I'm using: "cman-2.0.115-1.el5_4.9", "rgmanager-2.0.52-1.el5.centos.2",
"libvirt-0.6.3-20.1.el5_4"
I'm missing something on the "cluster.conf"??? Or at the libvirtd daemon?¿
Thanks for your help!
Alex.
