I added support for 'uri' parameter and moved some functions into
util/Python/utils.py in order not to lose them from the code and keep
them accessible for other tests.

It's better not to use libvirt API to check the result of one
another API.
We should use native approach to do the checking. So I insist
on the original checking.

I agree with this, the migrate.py use this too.
could you help clean migrate.py along with this together?
If we put this in utils.py, It's better not to accept
"logger" argument just like other utilities do
If we create a ssh-keygen and ssh_tunnel as a standalone
testcase. we will use the connect
for all of following testcases rather than setup a ssh
connection in each case. This will be good.
