We're doing a callback to the CIMOM here, asking the CIMOM to create an 
instance of Virt_MigrationJob for us.  The CIMOM is responding saying 
that our request is unsupported.

Can you check the following setting:

# cat /etc/Pegasus/cimserver_planned.conf  | grep 
repositoryIsDefaultInstanceProvider

or

# cat /etc/Pegasus/cimserver_current.conf  | grep 
repositoryIsDefaultInstanceProvider

You should see this set to:
repositoryIsDefaultInstanceProvider=true

If it's not, can you try running the following command:

cimconfig -s repositoryIsDefaultInstanceProvider=true -p

Then be sure to restart the CIMOM so it picks up the changes.  This 
tells Pegasus that we would like it to enable it's default provider for 
generating instances.

Let me know if this doesn't resolve the issue.
