[et-mgmt-tools] koan on RHEL-4, missing dependencies...

[Michael DeHaan]

I've just noticed that koan on RHEL-4 tries to overzealously import 
virtualization features, even when not using the --virt-parameter.  This 
can result in --replace-self not working
on older systems.

If you are trying to get --replace-self in koan to work on system and 
running into trouble because of missing virtualization modules, here's a 
patch:

This will be included in the next release of koan and will checked in 
shortly.
