Hi Przemek,
Thank you for your response, It's really provided us breakthrough.
After setting up DPDK on compute node for stable/kilo, Trying to set up
Openstack stable/liberty all-in-one setup, At present not able to get the IP
allocation for the vhost type instances through DHCP. Also tried assigning IP's
manually to them but the inter-VM communication also not happening,

Getting memory backing issues with qemu parameter passing
You should be able to clone networking-ovs-dpdk, switch to kilo branch, ÿand
run
python setup.py install
in the root of networking-ovs-dpdk, that should install agent and mech driver.
Then you would need to enable mech driver (ovsdpdk) on the controller in the
/etc/neutron/plugins/ml2/ml2_conf.ini
And run the right agent on the computes (networking-ovs-dpdk-agent).
ÿ
ÿ
There should be pip packeges of networking-ovs-dpdk available shortly,
I’ll let you know when that happens.

ÿ
Hi Przemek,ÿ
Thank you so much for your quick response.
The
guide(https://github.com/openstack/networking-ovs-dpdk/blob/stable/kilo/doc/source/getstarted/ubuntu.rst)
which you have suggested that is for openstack vhost user installations with
devstack.
Can't we have any reference for including ovs-dpdk mechanisam driver for
openstack Ubuntu distribution which we are following for
compute+controller node setup?"
We are facing below listed issues With the current approach of setting up
openstack kilo interactively + replacing ovs with ovs-dpdk enabled and Instance
creation in openstack withÿ
passing that instance id to QEMU command line which further passes the
vhost-user sockets to instances for enabling the DPDK libraries in it.ÿ
1. Created a flavor m1.hugepages which is backed by hugepage memory, unable to
spawn instance with this flavor – Getting a issue like: No matching
hugetlbfs for the number of hugepages assigned to the flavor.ÿ
2. Passing socket info to instances via qemu manually and instnaces created are
not persistent.ÿ
Now as you suggested, we are looking in enabling ovsdpdk ml2 mechanism driver
and agent all of that in our openstack ubuntu distribution.ÿ
Would be really appriciate if get any help or ref with explanation.ÿ
We are using compute + controller node setup and we are using following
software platform on compute node:
_____________
Openstack: Kilo
Distribution: Ubuntu 14.04
OVS Version: 2.4.0
DPDK 2.0.0

I haven’t tried that approach not sure if that would work, it seems
clunky.ÿ
ÿ
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.ÿ

ÿ
Hi Przemek,ÿ
Thank you so much for sharing the ref guide.ÿ
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 passing
that instance id to QEMU command line which further passes the vhost-user
sockets to instances, enabling the DPDK libraries in it.ÿ
Isn't this the correct way of integrating ovs-dpdk with openstack?ÿ

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

Successfully setup DPDK OVS with vhostuserÿ
Hi Przemek,ÿ
We have configured theÿaccelerated data path between a physical interface to
the VM using openvswitch netdev-dpdk with vhost-user support. The VM created
with this special data path and vhost library, I am calling as DPDK instance.
If assigning ip manually to the newly created Cirros VM instance, We are able
to make 2 VM's to communicate on the same compute node. Else it's not
associating any ip through DHCP though DHCP is in compute node only.ÿ
Yes it's a compute + controller node setup and we are using following software
platform on compute node:ÿ

What do you mean by DPDK instance?
Are you able to communicate with other VM's on the same compute node?

this is at least compute+ controller setup)
Best regards
