The build of vhost lib requires fuse development package. It is turned off by
default so as not to break DPDK build.

This vhost lib is based on old vhost example, and there are still plenty of

This vhost lib consists of five APIs plus several other helper routines
for feature disable/enable.
1) rte_vhost_driver_register to register vhost driver to the system.
2) rte_vhost_driver_callback_register to register the callback. Callbacks are
called when virtio device is ready for polling or
This patch does simple split of the original vhost example source files.
vhost rx/tx functions virtio_dev_rx/tx are copied from main.c to new file
vhost_rxtx.c.
main.c and main.h are removed. A new vhost example patchset will be submitted
later based on these two files.

This set of patches transforms and refactors vhost example to a user
space vhost cuse library. This library implements a user space vhost
cuse driver, and provides generic APIs for user space ethernet vswitch
to integrate us-vhost for fast packet switching with guest virtio.

I am concerned about its performance caused by too many memcpy(). Specifically,
on Rx side, kernel NIC driver needs to copy packets to skb, then af_packet
copies packets to AF_PACKET buffer which are mapped to user space, and then
those packets to be copied to DPDK mbuf. In addition, 3 copies

When I execute testpmd as shown below, it runs to the prompt apparently

Any suggestions as to why this is happening?

Bruce, Olivier,
What is the reason to remove this field? Please explain the rationale of
removing this field.
We previously agreed we need to provide an easy and standard mechanism for
applications to extend the mandatory per buffer metadata (mbuf) with optional

The patch set supports VxLAN on Fortville based on current mbuf structure. When
Bruce's new mbuf structure is done, there will be minor changes later.
It includes:
- Support VxLAN packet identification by configuring tunneling UDP port.
- Support VxLAN packet filters. It uses MAC and VLAN to

In this case the 'vhost' example is probably what you're looking for.
It supports VM2VM and VM to external traffic.
