You can snapshot the environment after Lago finishes the bootstrap
stages with `lago snapshot` and then roll back to the snapshot when
you need to.

You just need to intialize the environment manually with 'lago init',
'lago ovirt reposetup ...' 'lago deploy' and then run the initial
tests one by one with 'lago ovirt runtest' instead of letting
`runsuit.sh` do it all for you.

Alternatively you could possibly remove some of the symlinks from the
'test-scenarious' directory to leave just the ones you need and then
use `runsuit.sh` to get the the desired state before snapshotting.

'lago ovirt runtest' just runs nose, but its probably redirecting I/O
in a way that would not let you interact with a debugger. But you can
try... 'runsuit.sh' adds its own layers of redirection, so working
through it will probably be more challenging.
