Building and Installing:
------------------------
-Required: DPDK 2.1
+Required: DPDK 2.2
Optional (if building with vhost-cuse): `fuse`, `fuse-devel` (`libfuse-dev`
on Debian/Ubuntu)
1. Set `$DPDK_DIR`
```
- export DPDK_DIR=/usr/src/dpdk-2.1
+ export DPDK_DIR=/usr/src/dpdk-2.2
cd $DPDK_DIR
```
DPDK vhost:
-----------
-DPDK 2.1 supports two types of vhost:
+DPDK 2.2 supports two types of vhost:
1. vhost-user
2. vhost-cuse
DPDK vhost-user Prerequisites:
-------------------------
-1. DPDK 2.1 with vhost support enabled as documented in the "Building and
+1. DPDK 2.2 with vhost support enabled as documented in the "Building and
Installing section"
2. QEMU version v2.1.0+
-numa node,memdev=mem -mem-prealloc
```
+3. Optional: Enable multiqueue support
+ QEMU needs to be configured with multiple queues and the number queues
+ must be less or equal to Open vSwitch other_config:n-dpdk-rxqs.
+ The $q below is the number of queues.
+ The $v is the number of vectors, which is '$q x 2 + 2'.
+
+ ```
+ -chardev socket,id=char2,path=/usr/local/var/run/openvswitch/vhost-user-2
+ -netdev type=vhost-user,id=mynet2,chardev=char2,vhostforce,queues=$q
+ -device virtio-net-pci,mac=00:00:00:00:00:02,netdev=mynet2,mq=on,vectors=$v
+ ```
+
DPDK vhost-cuse:
----------------
DPDK vhost-cuse Prerequisites:
-------------------------
-1. DPDK 2.1 with vhost support enabled as documented in the "Building and
+1. DPDK 2.2 with vhost support enabled as documented in the "Building and
Installing section"
As an additional step, you must enable vhost-cuse in DPDK by setting the
following additional flag in `config/common_linuxapp`:
