Gareth -

Thanks for your input.  I believe the syntax I have for OpenWbem is
correct.  It looks like this:

# owcimindicationlistener -u http://localhost/root/cimv2 -f 'SELECT *
FROM CIM_InstCreation'

The reason I think the syntax is correct is because the output looks
like this:
...

However, when I try this: 

# owcimindicationlistener -u http://localhost/root/cimv2 -f 'SELECT *
FROM Xen_ComputerSystemIndication'

I get this:
...
[1115703616] safeLibCreate::create called.  createFuncName =
createIndicationRepLayer
[1115703616] Got query statement (SELECT * FROM
Xen_ComputerSystemCreation) in wql1
[1115703616] query is for indication class: Xen_ComputerSystemCreation
[1115703616] isaClassNames =
[1115703616] Found 0 providers for the subscription
[1115703616] Indication Server Subscriptions: No work after 1 sec. I'm
not waiting any longer

I get the same result if I try the interop namespace, or
Xen_CopmuterSystemIndication/Creation/Deletion/Modification.  BTW, the
Xen indication stuff shows up only in root/cimv2 - there is nothing in
Interop.  Also, there is no Xen_CopmuterSystemIndication - just
Xen_CopmuterSystemCreation/Deletion/Modification.

The result from CIM_InstCreation got me looking at
owprovindIndicationRepLayer where I realized there were a few functions
missing from the Xen provider, namely: getIndicationProvider,
getIndicationProviderInfo, and getIndicationProviderInfoWithEnv.

I was going to keep looking down that path. The functions have
structures passed into them which I have not quite matched to ours (I'm
pretty sure they're there, I just haven't gotten there yet).  Let me
know if that sounds like a reasonable plan.
