The both are actually\ndoing the same thing: a vhost-net implementation in user space. But they\nare not exactly the same thing.\n\nFirstly, vhost-cuse is harder for use; no one seems to care it, either.\nFurthermore, since v2.1, a large majority of development effort has gone\nto vhost-user. For example, we extended the vhost-user spec to add the\nmultiple queue support. We also added the vhost-user live migration at\nv16.04 and the latest one, vhost-user reconnect that allows vhost app\nrestart without restarting the guest. Both of them are very important\nfeatures for product usage and none of them works for vhost-cuse.\n\nYou now see that the difference between vhost-user and vhost-cuse is\nbig (and will be bigger and bigger as time moves forward), that you\nshould never use vhost-cuse, that we should drop it completely.\n\nThe remove would also result to a much cleaner code base, allowing us\nto do all kinds of extending easier.\n\nSo here to mark vhost-cuse as deprecated in this release and will be\nremoved in the next release (v16.11).\n\nSigned-off-by: Yuanhan Liu <yuanhan.liu@linux.intel.com>\n---\n doc/guides/rel_notes/deprecation.rst | 4 ++++\n 1 file changed, 4 insertions(+)", "diff": "diff --git a/doc/guides/rel_notes/deprecation.rst b/doc/guides/rel_notes/deprecation.rst\nindex f502f86..ee99558 100644\n--- a/doc/guides/rel_notes/deprecation.rst\n+++ b/doc/guides/rel_notes/deprecation.rst\n@@ -41,3 +41,7 @@ Deprecation Notices\n * The mempool functions for single/multi producer/consumer are deprecated and\n will be removed in 16.11.\n It is replaced by rte_mempool_generic_get/put functions.\n+\n+* The vhost-cuse will be removed in 16.11.
