[PATCH v5 0/5] vhost-user block device backend implementation
Posted by Coiby Xu 5 years, 11 months ago 
v5:
 * re-use vu_kick_cb in libvhost-user
 * keeping processing VhostUserMsg in the same coroutine until there is
   detachment/attachment of AIOContext
 * Spawn separate coroutine for each VuVirtqElement
 * Other changes including relocating vhost-user-blk-server.c, coding
   style etc.

v4:
 * add object properties in class_init
 * relocate vhost-user-blk-test
 * other changes including using SocketAddress, coding style, etc.

v3:
 * separate generic vhost-user-server code from vhost-user-blk-server
   code
 * re-write vu_message_read and kick hander function as coroutines to
   directly call blk_co_preadv, blk_co_pwritev, etc.
 * add aio_context notifier functions to support multi-threading model
 * other fixes regarding coding style, warning report, etc.

v2:
 * Only enable this feauture for Linux because eventfd is a Linux-specific
   feature


This patch series is an implementation of vhost-user block device
backend server, thanks to Stefan and Kevin's guidance.

Vhost-user block device backend server is a UserCreatable object and can be
started using object_add,

 (qemu) object_add vhost-user-blk-server,id=ID,unix-socket=/tmp/vhost-user-blk_vhost.socket,node-name=DRIVE_NAME,writable=off,blk-size=512
 (qemu) object_del ID

or appending the "-object" option when starting QEMU,

  $ -object vhost-user-blk-server,id=disk,unix-socket=/tmp/vhost-user-blk_vhost.socket,node-name=DRIVE_NAME,writable=off,blk-size=512

Then vhost-user client can connect to the server backend.
For example, QEMU could act as a client,

  $ -m 256 -object memory-backend-memfd,id=mem,size=256M,share=on -numa node,memdev=mem -chardev socket,id=char1,path=/tmp/vhost-user-blk_vhost.socket -device vhost-user-blk-pci,id=blk0,chardev=char1

And guest OS could access this vhost-user block device after mouting it.

Coiby Xu (5):
  allow vu_message_read to be replaced
  generic vhost user server
  vhost-user block device backend server
  a standone-alone tool to directly share disk image file via vhost-user
    protocol
  new qTest case to test the vhost-user-blk-server
