It is about VMs on IOMMU capable systems. What if you need to use SRIOV
with IXGBE, or IGB devices?
For some DPDK cases, like Mellanox or virtio, you do not need to use
VFIO/UIO into the guests, so

Hi Przemek,
Thank you so much for sharing the ref guide.
Would be appreciate if clear one doubt.
At present we are setting up openstack kilo interactively and further
replacing ovs with ovs-dpdk enabled.
Once the above setup done, We are creating instance in openstack and

The nb_rx_queues and nb_tx_queues are initialised before
the tx_queue and rx_queue arrays are allocated. The arrays
are allocated when the ethdev port is started.
If any of the following functions are called before the ethdev
port is started there is a segmentation fault:

I haven't tried that approach not sure if that would work, it seems clunky.
If you enable ovsdpdk ml2 mechanism driver and agent all of that (add ports to
ovs with the right type, pass the sockets to qemu) would be done by OpenStack.

Hi all,
When running the multi process example, does anybody know that why increasing
the number of mbufs, the performance gets dropped.
In multi process example, there are two macros which are related to the number
of mbufs

In HTML and PDF guides, it is clear in the header that the doc
is related to the DPDK.
So "DPDK" is redundant and can be removed from FAQ and release notes

HI Abhijeet,
For Kilo you need to use ovsdpdk mechanism driver and a matching agent to
integrate ovs-dpdk with OpenStack.
The guide you are following only talks about running ovs-dpdk not how it should
be integrated with OpenStack.
Please follow this guide:

To claim that we support vhost-user live migration support:
SET_LOG_BASE request will be send only when this feature flag
is set.
Besides this flag, we actually need another feature flag set
to make vhost-user live migration work: VHOST_F_LOG_ALL.
Which, however, has been enabled long time ago.

It's actually a feature already enabled in Linux kernel. What we need to
do is simply to claim that we support such feature, and nothing else.
With that, the guest will send GARP messages after live migration.

Introduce vhost_log_write() helper function to log the dirty pages we
touched. Page size is harded code to 4096 (VHOST_LOG_PAGE), and each
log is presented by 1 bit.
Therefore, vhost_log_write() simply finds the right bit for related
page we are gonna change, and set it to 1. dev->log_base denotes
VHOST_USER_SET_LOG_BASE request is used to tell the backend (dpdk
vhost-user) where we should log dirty pages, and how big the log
buffer is.
This request introduces a new payload:
typedef struct VhostUserLog {
uint64_t mmap_size;
uint64_t mmap_offset;
} VhostUserL
This patch set adds the vhost-user live migration support.
The major task behind that is to log pages we touched during
live migration, including used vring and desc buffer. So, this
patch set is basically about adding vhost log support, and
using it.

No need to bind them by default, and nothing prevents you from calling them
