unable to install DPDK in Devstack(in Ubuntu 16.04 version)

I am trying to install Devstack with DPDK in Ubuntu 16.04. I have installed Devstack (Rocky version) in Ubuntu machine.
Reference link to install the devstack is mentioned below.
https://docs.openstack.org/devstack/latest/
Devstack was successfully installed. However, i am trying to validate DPDK in it.
When i check the status of both DPDK and openvswitch. It is showing the status of openvswitch alone.
Can anyone, please let me know how to install dpdk manually or along with Devstack?
I haven't tried devstack with ovs-dpdk, but if you are using ovs which is compiled with dpdk, then you can start from 'setup Hugepage' section in following doc manually:
http://docs.openvswitch.org/en/latest/intro/install/dpdk/
I also notice networking-ovs-dpdk plugin which can be used in devstack.

php7.0-mcrypt can't install on ubuntu14.04

phpmyadmin show error [ The mcrypt extension is missing. Please check your PHP configuration.] on nginx. My PHP version is PHP 7.0.33-1+ubuntu14.04.1+deb.sury.org+1 (cli).
When I install php7.0-mcrypt, package doesn't exist.How to install php7.0-mcrypt?
As I understand from your message, you're using ubuntu 14.04. I recommend you upgrade your system. You could find this package in some latest reseases.
Or you could install this package manually wget http://cz.archive.ubuntu.com/ubuntu/pool/universe/p/php7.0/php7.0-mcrypt_7.0.33-0ubuntu0.16.04.4_amd64.deb && sudo dpkg -i php7.0-mcrypt_7.0.33-0ubuntu0.16.04.4_amd64.deb. But be careful, you could face some dependency hell and damage your OS.

Error while installing tripleo Client Library

When i try to download tripleo Client using command
yum install -y python-tripleoclient ceph-ansible
On Centos 7.5 , I am getting error curl#60 - "Peer's Certificate has expired."
This has nothing to do with tripleo client itself. You are using some temporary yum repositories which were recycled.
My favorite hacking approach is to use pip to install it:
pip install python-tripleoclient
This is also documented on https://docs.openstack.org/python-tripleoclient/latest/installation.html

Zookeeper set up for Kaa

I'm trying to set up kaa v0.10.0 on ubuntu 14.04 LTS. To install zookeper I used the following command.
sudo apt-get install zookeeper
But it fails to start when I start the kaa-node service.
But when I install the package zookeeperd (seen in older kaa versions documentation sudo apt-get install zookeeperd), it works fine.
Can anyone please clarify which is the correct zookeeper package for kaa 0.10? - zookeeper or zookeeperd
From few of my experiences in deploying Kaa, I don't think Zookeeper will start automatically after installation, perhaps you can start it manually before starting Kaa-node.
