Is your ncat segfaulting? It looks like it from this output. Have you
tried running your ncat with a UNIX socket independently of this test?
Is this the first time you've tried this test in this environment, or
is this a regression for you?

This won't work because we need run_tests.sh to setup the run_migration()
call. The only ways to run migration tests separately are
$ ./run_tests.sh its-migration
and
$ tests/its-migration
For the second one you need to do 'make standalone' first.

The test doesn't get your input because of the '</dev/null' in run_qemu(),
which ./arm-run calls. So it's not hanging it's just waiting forever on
the key press.
