This article describes how to install OpenStack on [[Virtuozzo]] 7.
== Introduction ==
This howto describes steps by step installation of Virtuozzo 7 supports OpenStack with [[as cloud management solution since version 6. With Virtuozzo]] 7we are going to add a lot of new capabilities to OpenStack integration.
Execute the following commands within This guide describes two ways of installing OpenStack on Virtuozzo nodes. The first is for quick/development/POC needs. The second is for production. Please keep in mind that devstack allows you Virtuozzo 7 to install OpenStack for demo/POC/development purposes only. That means it will be reset after host as root:reboot.
Install RDO repoYou need the following infrastructure to setup OpenStack with Virtuozzo 7:#controller host: physical host or virtual machine with at least 4CPU, 8GB RAM, 150GB disk. This host will act as a controller and Virtuozzo containers host.#compute host: physical host or virtual machine with at least 4CPU, 8GB RAM, 150GB disk. This host will act as a virtual machines host.
$ yum install -y https://rdoproject.org/repos/rdo-release.rpm== Prerequisites ==
You need to install and update your Virtuozzo nodes first. Install EPEL repoVirtuozzo 7 on your controller and compute hosts as usual. You can use basic (local) or Virtuozzo Storage. Update Virtuozzo hosts $ yum update -y If you have br0 bridge configured as an IP interface, then you should move an IP address assigned to it to the physical ethernet interface bridged to br0.You can check you configuration with the following command:  $ if=$(brctl show | grep '^br0' | awk ' { print $4 }') && addr=$(ip addr | grep -w 'br0' | grep inet | awk ' {print $2} ') && gw=$(ip route | grep default | awk ' { print $3 } ') && echo "My interface is '$if', gateway is '$gw', IP address '$addr'" For instance you have the following output after execution the above script:  My interface is 'en33', gateway is '192.168.190.2', IP address '192.168.190.134/24'. Then edit your /etc/sysconfig/network-scripts/ifcfg-ens33 to have the following content and remove BRIDGE="br0" string from it: ... ONBOOT=yes IPADDR=192.168.190.134 GATEWAY=192.168.190.2 PREFIX=24 ... Remove /etc/sysconfig/network-scripts/ifcfg-br0 file.  $ rm /etc/sysconfig/network-scripts/ifcfg-br0
Then restart network service:  $ systemctl restart network == Setup OpenStack Controller Node with Virtuozzo Containers Support (*Developer/POC Setup*) == <!--T:1--> <!--T:3-->You are able to setup OpenStack controller node together with compute node on the same server for demo or test purpose. In this case compute node with Virtuozzo Containers support will be deployed. You can add another compute node with containers or VMs anytime you want as described in Setup OpenStack Compute Node section. Git must be installed on all your Virtuozzo nodes: $ yum install git -y Clone virtuozzo scripts:  $ cd /vz $ git clone https://github.com/virtuozzo/virtuozzo-openstack-scripts $ cd virtuozzo-openstack-scripts If you want to use Virtuozzo Storage with OpenStack and your Virtuozzo Storage is running on another node and not on the compute you need to setup Virtuozzo Storage client and authorize compute node in the Virtuozzo Storage Cluster.  Setup Virtuozzo Storage client: $ yum install vstorage-client -yCheck cluster discovery is working fine first: $ vstorage discoverOutput will show the discovered clusters.Now you need to authenticate controller node on the Virtuozzo Storage cluster: $ vstorage -c $CLUSTER_NAME auth-nodeEnter the virtuozzo storage cluster password and press Enter. Check the cluster properties: $ vstorage -c $CLUSTER_NAME topOutput will show Virtuozzo storage cluster properties and state. Configure the script on the CONTROLLER node. Please read full script description here https://github.com/virtuozzo/virtuozzo-openstack-scripts/blob/master/README.md Example: $ source vzrc --host_ip 10.24.41.25 --password Virtuozzo1! --use_provider_network true --fixed_range 192.168.0.0/24 --floating_range 10.24.41.0/24 --floating_pool "start=10.24.41.151,end=10.24.41.199" --public_gateway 10.24.41.1 --gateway 192.168.0.1 --vzstorage vstorage1 --mode ALL  Run the script on your CONTROLLER node and follow instructions (if any): $ ./setup_devstack_vz7.sh Installation can take up to 30 minutes depending on your Internet connection speed. Finished! == Setup OpenStack Compute Node (*Developer/POC Setup*) == Git must be installed on all your Virtuozzo nodes: $ yum install git -y http Clone Virtuozzo scripts to your COMPUTE node: $ cd /vz $ git clone https://fedoragithub.com/virtuozzo/virtuozzo-openstack-scripts $ cd /vz/virtuozzo-openstack-scripts If you want to use Virtuozzo Storage with OpenStack and your Virtuozzo Storage is running on another node and not on the compute you need to setup Virtuozzo Storage client and authorize compute node in the Virtuozzo Cluster. Setup Virtuozzo Storage client: $ yum install vstorage-client -yCheck cluster discovery is working fine first: $ vstorage discoverOutput will show the discovered clusters.Now you need to authenticate controller node on the Virtuozzo Storage cluster: $ vstorage -c $CLUSTER_NAME auth-mirror01nodeEnter the virtuozzo storage cluster password and press Enter.rbcCheck the cluster properties: $ vstorage -c $CLUSTER_NAME topOutput will show the virtuozzo storage cluster properties and state. Configure the script on the COMPUTE node. Please read script description here https://github.rucom/virtuozzo/pubvirtuozzo-openstack-scripts/epelblob/master/epelREADME.md Example: $ source vzrc --host_ip 10.24.41.26 --password Virtuozzo1! --releaseuse_provider_network true -latest-7mode COMPUTE --controller 10.24.41.25  Run the script on your COMPUTE node and follow instructions (if any): $ ./setup_devstack_vz7.noarchsh == How to change Virtualization Type to Virtual Machines on the Compute Node == If you want to use virtual machines instead of containers on your compute node you need to change virtualization type to KVM on the selected compute node.rpm
Install required packagesOpen nova configuration file: $ yum install -y git patch redhat-lsb-core euca2ools mysql-connector-python scsi-target-utilsvi /etc/nova/nova.conf
