[Linux-cluster] fence_xvmd in RHEL5 with a virtual domU cluster

[Bernard Chew]

Hi,

I follow the steps below to use fence_xvmd in RHEL5;

(1) configure dom0 like a 1-node cluster 
(2) Add "<fence_xvmd/>" to cluster.conf in dom0 as a child of the
"<cluster>" tag.
(3) dd if=/dev/urandom of=/etc/cluster/fence_xvm.key bs=4096 count=1
(4) scp /etc/cluster/fence_xvm.key root virtual_node_1:/etc/cluster
(5) scp /etc/cluster/fence_xvm.key root virtual_node_2:/etc/cluster
(6) Start cman on dom0 - this should start fence_xvmd for you

However, I encounter the following errors while running "fence_xvmd
-fddddddddd" on the dom0 node and "fence_xvm -H <domain_name> -o null"
on one of the guests;

Any idea why?
