[Libguestfs] [PATCH] customize: Test that the --root-password parameter works.

[Richard W.M. Jones]

This is the second half of the patch series posted yesterday (see:
"[PATCH 0/2] builder: Add test that a serial console is set up for
guest templates we supply.").

This checks that our code to change passwords works on real guests.

It creates a real guest using virt-builder with the --root-password
option, then boots it up and tries to log in with the root password.

Interaction with the guest is afforded by the perl Expect module.

Rich.
