Hi again,
I have found that when I run the comand this way:
fence_xvmd -fddddd -I vnet0
Debugging threshold is now 5

Timed out waiting for response
and doesn´t fence.
So your vm hosts are not on the eth0 network of Domain-0, but they are
on the private network. IIRC, fence_xvmd listens, by default, on eth0.
You can overcome this by, if you use RHEL 5.3, adding -I vnet0 ( or
whatever device which domain-0 uses to communicate with domU ) into the
fence_xvmd 's parameter list .IIRC, this parm -I does not exist on RHEL
5.2 or ealier. You can do that by adding FENCE_XVMD_OPTS="-I vnet0" into
/etc/sysconfig/cman.
