→Installing OpenStack with help of packstack on Virtuozzo 7 (*Production Setup*)
Virtuozzo 7 supports OpenStack as cloud management solution since version 6. With Virtuozzo 7 we are going to add a lot of new capabilities to OpenStack integration.
This guide allows you to install describes two ways of installing OpenStack with on Virtuozzo nodes with a help of Devstack tools. Devstack The first is for quick/development/POC needs. The second is for production. Please keep in mind that devstack allows you to install stateless OpenStack for demo purpose that /POC/development purposes only. That means it will be reset after host reboot. So, the best platform to setup OpenStack in this case is virtual machines. Please note that OpenStack now does not support containers and virtual machines on the same node, thus you need at least two nodes to try containers and VMs management.
You need the following infrastructure to setup OpenStack with Virtuozzo 7:
$ yum update -y
If you have br0 bridge configured as an IP connection tracking interface, then you should be enabled for CT0move an IP address assigned to it to the physical ethernet interface bridged to br0. Please do You can check you configuration with the followingcommand:#Open the file /etc/modprobe.d/vz.conf#Change the line <code>options nf_conntrack ip_conntrack_disable_ve0 $ if=$(brctl show | grep '^br0' | awk ' { print $4 }') && addr=1</code> to <code>options nf_conntrack ip_conntrack_disable_ve0$(ip addr | grep -w 'br0' | grep inet | awk ' {print $2} ') && gw=0</code>$(ip route | grep default | awk ' { print $3 } ') && echo "My interface is '$if', gateway is '$gw', IP address '$addr'" #Reboot For instance you have the following output after execution the systemabove script:
== 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:
Output will show the discovered clusters.
Now you need to authenticate controller node on the Virtuozzo Storage cluster:
$ vstorage -c $CLUSTER_NAME auth-node -P
Enter the virtuozzo storage cluster password and press Enter.
Check the cluster properties:
Output will show Virtuozzo storage cluster properties and state.
Configure the script on the CONTROLLER node. Please read full script description here [http://www.example.com link title]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 192.168.10.0/24 --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):
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
Clone Virtuozzo scripts to your COMPUTE node:
Output will show the discovered clusters.
Now you need to authenticate controller node on the Virtuozzo Storage cluster:
$ vstorage -c $CLUSTER_NAME auth-node -P
Enter the virtuozzo storage cluster password and press Enter.
Check the cluster properties:
Output will show the virtuozzo storage cluster properties and state.
Configure the script on the COMPUTE node. Please read script description here https://github.com/virtuozzo/virtuozzo-openstack-scripblobscripts/blob/master/README.md
Example:
$ ./setup_devstack_vz7.sh
== How to change Virtualiztion 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.
Change the following lines:
[libvirt] ... virt_type = kvmparallels images_type = qcow2 connection_uri = qemuvz:///system
Delete the line:
inject_partition = -2
Save the file.
# Run ./setup_devstack_vz7.sh with options you need.

Please use this chapter if you are going to run containers OR virtual machines on your compute node, but not containers AND virtual machines simultaneously. If you need to run containers and VMs simultaneously, please use next chapter. * Follow instructions on [http://docs.openstack.org/libertynewton/install-guide-rdo/nova-compute-install.html OpenStack.org]

* Then restart nova-compute service:
$ systemctl restart openstack-nova-compute.service * If you plan to run Virtual Machines on your Compute node, change 'images_type' parameter to 'qcow2' == Install and configure a block storage node on [[Virtuozzo]] 7 (*Production Setup*) == <!--T:16--> <!--T:17-->If you are going to run containers AND virtual machines simultaneously on your compute node you have to use this approach. * Follow instructions on [http://docs.openstack.org/mitaka/install-guide-rdo/cinder-controller-install.html OpenStack.org]* In addition to above instructions change /etc/cinder/cinder.conf: [DEFAULT] ... enabled_backends = lvmdriver-1,vstorage-ploop,vstorage-qcow2 ...
