I mean, in order to run FVT test suite, Kimchi must be installed on one 
of the supported distro.  Test suite may not be on the same target 
machine where it is suppose to run but it can also be triggered from 
different machine against the target machine.

Exactly, Mock is an object that simulates the behavior of a real object 
in controlled ways. Mock objects are used in unit testing.
With MockModel it still helps you in testing certain functionality but 
on simulated data/environment.

On the other hand Functional Verification Test - (also can be called as 
Integration Test), helps testing a slice of functionality on a real 
system. This will test many methods and may interact with dependencies 
involved.

We maintained a config file, which has a section to provide the session 
details (user, host, ssl port num etc) of the target machine against 
which test suite will run. End user have to update the config file 
before executing the test suite.

For example FVT test cases we developed:
Test case to perform Virtual Machine life-cycle operations.
Test case for debug report generations.
Test case for repository creation/updation/deletion.
Test case for create/modify/update various template scenario's.
Test case to create/activate/de-activate/delete of network interfaces 
like isolation, NAT and bridge network interfaces.
Test case to create/activate/deactivate/delete of storage pools of 
various types (DIR, SCSI, iSCSI, Logical) and storage volumes operations 
(create/update/delete) on each of these storage pools.
and so on....
