[Qemu-devel] [PATCH v2 25/34] test/qgraph: virtio-balloon test node

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

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

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