2018-06-01vhost-blk: turn on pre-defined RO feature bitChangpeng Liu1-13/+35
Read only feature shouldn't be negotiable, because if the backend device reported Read only feature supported, QEMU host driver shouldn't change backend's RO attribute. While here, also enable the vhost-user-blk test utility to test RO feature.

2018-01-18contrib/vhost-user-blk: introduce a vhost-user-blk sample applicationChangpeng Liu2-0/+546
This commit introduces a vhost-user-blk backend device, it uses UNIX domain socket to communicate with QEMU. The vhost-user-blk sample application should be used with QEMU vhost-user-blk-pci device. To use it, complie with: make vhost-user-blk and start like this: vhost-user-blk -b /dev/sdb -s /path/vhost.socket Signed-off-by: Changpeng Liu <changpeng.liu@intel.com> Reviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Michael S.
