This article describes how to install Virtuozzo Infrastructure Platform on [[Virtuozzo]] 7.
== Introduction ==
You need the following infrastructure to setup Virtuozzo Infrastructure Platform on Virtuozzo 7:
# Three controller hosts: physical host or virtual machine with at least 4CPU, 8GB RAM, 150GB disk. These hosts will act as controller and Virtuozzo containers host.
# Compute hosts: physical host or virtual machine with at least 4CPU, 8GB RAM, 150GB disk.
# Configured VStorage: a set of
 
== Prerequisites ==
 
You need to install and update your Virtuozzo nodes first. Install Virtuozzo 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
 
== Installing Virtuozzo Infrastructure Platform on [[Virtuozzo]] 7 using packstack ==
 
* Install Virtuozzo Platform Release package to all Virtuozzo OpenStack nodes:
 
$ yum install vz-platform-release
 
* Install packstack package:
 
$ yum install openstack-packstack
 
* Download sample Vz7 packstack answer file:
 
$ wget https://raw.githubusercontent.com/virtuozzo/virtuozzo-openstack-scripts/master/vz7-packstack-ocata.txt
 
* Edit vz7-packstack-ocata.txt enabling/disabling necessary services
* Replace all references to 'localhost' and '127.0.0.1' host addresses to correct valuses
* Set all passwords parameters containing PW_PLACEHOLDER string to some meaninful values
* If you are going to use Virtuozzo Storage as a Cinder Volume backend set the following parameters:
 
# Enable Virtuozzo Storage
CONFIG_VSTORAGE_ENABLED=y
 
# VStorage cluster name.
CONFIG_VSTORAGE_CLUSTER_NAME=
 
# VStorage cluster password.
CONFIG_VSTORAGE_CLUSTER_PASSWORD=
 
# Bridge mappings
CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS=extnet1:br-ex
 
# Bridge interfaces
CONFIG_NEUTRON_OVS_BRIDGE_IFACES=br-ex:eth0
 
# Bridge mapping for compute node
CONFIG_NEUTRON_OVS_BRIDGES_COMPUTE=extnet1:br-ex
 
* Then run packstack:
 
$ packstack --answer-file=vz7-packstack-ocata.txt
 
== Generate and Upload images == <!--T:18-->
 
* Upload the image to glance:
 
$ glance image-create --name centos7-exe --disk-format ploop --min-ram 512 --min-disk 1 --container-format bare --property vm_mode=exe --property hypervisor_type=vz --property cinder_img_volume_type=vstorage-ploop --file centos7-exe.hds
 
$ glance image-create --name centos7-hvm --disk-format qcow2 --min-ram 1024 --min-disk 10 --container-format bare --property cinder_img_volume_type=vstorage-qcow2 --file CentOS-7-x86_64-GenericCloud.qcow2
 
* CentOS image one can get here [http://cloud.centos.org/centos/7/images/CentOS-7-x86_64-GenericCloud.qcow2 ]
