This patch fixes the 'not checking the returns from the CIMOM in
References and ReferenceNames' problem.
The key name checking is really not necessary to fix this problem. (As
an aside, I don't know if any key ties the Host ComputerSystem class and
the Virtual (Xen_ComputerSystem) class.)
This patch fixes the Xen_HostedComputerSystem file. It is quite trivial
to do it for the other classes, but I will wait till the SMASH issue is
settled.

The problem with this patch, and Raj's previous one apparently :-), is
that there is no filtering of object paths returned via upcalls to cimom
for instance names of the associated thing. For example, in
ReferenceNames() in Xen_HostedMemory.c we make an upcall to get all
instances of CIM_Memory when it is the target class. But Xen_Memory is
a subclass of CIM_Memory so you get instances of Xen_Memory (which is
the source class) and associate it with itself or other instances of
Xen_Memory for other domains. If I list associations of Xen_Memory for
domain 1 using this patch, I get a Xen_HostedMemory association for each
Xen_Memory object produced by other domains.
Make sense? I'm quite tired now so this may be a smoked explanation
:-).
Thanks,
Jim
