It seems you don't have TUT_UnixProcess.py on the right place.

As written in
https://fedorahosted.org/openlmi/wiki/ProviderTutorialImplementationPytho...,
it should be installed in /usr/lib/python2.7/site-packages/tutorial (or
whatever your Python site directory is) and appropriate .reg file should
refer it with full path:

[TUT_UnixProcess]
provider: /usr/lib/python2.7/site-packages/tutorial/TUT_UnixProcess.py
location: pyCmpiProvider
type: instance method
namespace: root/cimv2

If something goes wrong, you can debug/troubleshoot the provider loading
in /usr/lib/python2.7/site-packages/pywbem/cim_provider2.py - just add
following code before imp.find_module() call:

	print >>sys.stderr, self.provider_module_name, provider

and run Pegasus with using this command:
$ cimserver daemon=false forceProviderProcesses=false

All 'print' will go to stderr, as described in Debugging chapter in the
tutorial.
