[Qemu-devel] [PULL 10/13] tests: virtio-9p: add attach operation test |
Date: |
Wed, 4 Jan 2017 09:21:44 +0100 |
The attach operation is used to establish a connection between the
client and the server. After this, the client is able to access the
underlying filesystem and do I/O.
This test simply ensures the operation succeeds without error.
