[ovirt-devel] Custom fencing with virsh_fence

[Adam Litke]

Hi all,

I am trying to configure custom fencing using fence_virsh in order to
test out fencing flows with my virtualized oVirt hosts.  I'm getting a
failure when clicking the "Test" button.  Can someone help me to
diagnose the problem?  I have applied the following settings using
engine-config:

~/ovirt-engine/bin/engine-config -s CustomVdsFenceType="xxxvirt"
~/ovirt-engine/bin/engine-config -s CustomFenceAgentMapping="xxxvirt=virsh"
 ~/ovirt-engine/bin/engine-config -s CustomVdsFenceOptionMapping="xxxvirt:address=ip,username=username,password=password"

(note that engine-config seems to arbitrarily limit the number of
mapped options to 3.  Seems like a bug to me).


Here is the log output in engine.log:
