→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: My interface is 'en33', gateway is '192.168.190.2', IP address '192.168.190.134/24'.
== 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:

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:
[libvirt]
...
virt_type = kvmparallels
images_type = qcow2
connection_uri = parallelsvz:///system
Delete the line:
# <code>git pull</code>
# Run ./setup_devstack_vz7.sh with options you need.
== Installing OpenStack with help of packstack on [[Virtuozzo]] 7 (*Production Setup*) ==
* 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
== Install and configure a nova controller node on [[Virtuozzo]] 7 (*Production Setup*) == <!--T:18-->
<!--T:19-->
* Follow instructions on [http://docs.openstack.org/mitakanewton/install-guide-rdo/nova-controller-install.html OpenStack.org]* Change disk_formats string in /etc/glance/glance-api.conf so that it contains 'ploop'. Like this: disk_formats = ami,ari,aki,vhd,vmdk,raw,qcow2,vdi,iso,ploop
* Unpack it
NOTE: this image was created for testing purposes only. Don't use it in production as is!
$ 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 ]
== Install and configure a compute node on [[Virtuozzo]] 7 (*Production Setup*) == <!--T:16-->
<!--T:17-->
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/mitakanewton/install-guide-rdo/nova-compute-install.html OpenStack.org]
* In addition to above instructions change /etc/nova/nova.conf:
vnc_keymap =
force_raw_images = False
pointer_model = ps2mouse
[libvirt]
...
vzstorage_mount_user = nova
vzstorage_mount_group = root
virt_type = parallels
images_type = ploop
connection_uri = parallelsvz:///system * Remove 'cpu_mode' parameter or set the following: cpu_mode = none
* Then restart 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:
[vstorage-ploop]
vzstorage_default_volume_format = parallelsploop
vzstorage_shares_config = /etc/cinder/vzstorage-shares-vstorage.conf
volume_driver = cinder.volume.drivers.vzstorage.VZStorageDriver
volume_backend_name = vstorage-qcow2
* Create /etc/cinder/vzstorage-shares-vstorage.conf with the following content:
YOUR-CLUSTER-NAME ["-u", "cinder", "-g", "root", "-m", "0770"]
$ cinder type-create vstorage-ploop
$ cinder type-key vstorage-ploop set volume_backend_name=vstorage-ploop * Create directory for storage logs: $ mkdir /var/log/pstorage * Authenticate your Virtuozzo Storage client nodes in oreser to allow them to mount cluster: $ echo $CLUSTER_PASSWD | vstorage auth-node -c YOUR-CLUSTER-NAME -P
* Then restart cinder services:
$ systemctl restart openstack-cinder-volume
== How to create a new ploop image ready to upload to Glance == <!--T:17-->
* Select os template. The following templates are possible: vzlinux-7, centos-7, ubuntu-16.04, ubuntu-14.04, debian-8.0, centos-6, debian-8.0-x86_64-minimal
$ ct=centos-7
* Create a new container based on necessary os distribution
$ prlctl create glance-$ct --vmtype ct --ostemplate $ct
* Set IP address and DNS to be able to connect to internet from the container
$ prlctl set glance-$ct --ipadd IPADDR --nameserver DNS_IPADDR
* Add additional network adapter
$ prlctl set glance-$ct --device-add net --network Bridged --dhcp on
* Start the container
$ prlctl start glance-$ct
* Install cloud-init packet
$ prlctl exec glance-$ct yum install cloud-init -y
* Stop the container and mount it
$ prlctl stop glance-$ct
$ prlctl mount glance-$ct
* Store the container uuid
$ uuid=$(vzlist glance-$ct | awk ' NR>1 { print $1 }')
* Remove the following modules from cloud.cfg
$ sed -i '/- growpart/d' /vz/root/$uuid/etc/cloud/cloud.cfg
$ sed -i '/- resizefs/d' /vz/root/$uuid/etc/cloud/cloud.cfg
* Prepare network scripts
cat > /vz/root/$uuid/etc/sysconfig/network-scripts/ifcfg-eth0 << _EOF
DEVICE=eth0
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=dhcp
_EOF
* If you need more than one network adapters within a container, make as many copies as you need
$ cp /vz/root/$uuid/etc/sysconfig/network-scripts/ifcfg-eth0 /vz/root/$uuid/etc/sysconfig/network-scripts/ifcfg-eth1
$ sed -i '/eth0/eth1' /vz/root/$uuid/etc/sysconfig/network-scripts/ifcfg-eth1
* Perform some cleanup
$ rm -f /vz/root/$uuid/etc/sysconfig/network-scripts/ifcfg-venet0*
$ rm -f /vz/root/$uuid/etc/resolv.conf
* Create ploop disk and copy files
$ mkdir /tmp/ploop-$ct
$ ploop init -s 950M /tmp/ploop-$ct/$ct.hds
$ mkdir /tmp/ploop-$ct/dst
$ ploop mount -m /tmp/ploop-$ct/dst /tmp/ploop-$ct/DiskDescriptor.xml
$ cp -Pr --preserve=all /vz/root/$uuid/* /tmp/ploop-$ct/dst/
$ ploop umount -m /tmp/ploop-$ct/dst/
* Unmount the container
$ prlctl umount glance-$ct
* Now the image tmp/ploop-$ct/$ct.hds is ready to be uploaded to Glance
