[Qemu-devel] [PATCH v2 20/34] test/qgraph: virtio-console test node

[Emanuele Giuseppe Esposito <e.emanuelegiuseppe@gmail.com>]

Convert tests/virtio-console-test in qgraph test node,
virtio-console-test. This test consumes a virtio-serial interface
and checks that its function return the expected values.

Note that this test does not allocate any virtio-console structure,
it's all done by the qtest walking graph mechanism
