<!--T:1-->
This howto article describes how to install OpenStack on [[Virtuozzo]] 7.== Introduction ==
Then restart network service: $ ./setup_devstack_for_vz7.sh HOST_IP PASSWORDsystemctl restart network
== Setup OpenStack Controller Node with Virtuozzo Containers Support (*Developer/POC Setup*) == <!--T:1-->
$ cd /vz
$ cd virtuozzo-openstack-scripts
Run the script on your CONTROLLER node and follow instructions (if any):
Clone Virtuozzo scripts to your COMPUTE node:
$ cd /vz
$ git clone https://github.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-nodeEnter the virtuozzo storage cluster password and press Enter. Check 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.com/virtuozzo/virtuozzo-openstack-scripts/blob/master/README.md Example: $ source vzrc --host_ip 10.24.41.26 --password Virtuozzo1! --use_provider_network true --mode COMPUTE --controller 10.24.41.25
Run the script on your COMPUTE node and follow instructions (if any):
[libvirt]
...
virt_type = parallels
images_type = ploopqcow2 connection_uri = parallels+unixvz:///system Delete the line:
inject_partition = -2
Save the file. Restart nova-compute service: $ su stack $ screen -rPress Ctrl-c $ sg libvirtd '/usr/bin/nova-compute --config-file /etc/nova/nova.conf' & echo $! >/vz/stack/status/stack/n-cpu.pid; fg || echo "n-cpu failed to start" | tee "/vz/stack/status/stack/n-cpu.failure" To exit from screen session:Press Ctrl+a+d == How to redeploy OpenStack on the same nodes == Your OpenStack setup will be reset after node restart. To redeploy OpenStack on the same nodes do the following:# <code>cd /vz/virtuozzo-openstack-scripts</code># <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.

* Follow instructions on [http://docs.openstack.org/libertynewton/install-guide-rdo/nova-controller-install.html OpenStack.org] * Download the container [http://updates.virtuozzo.com/server/virtuozzo/en_us/odin/7/techpreview-ct/centos7-exe.hds.tar.gz image]* Unpack it $ tar -xzvf centos7-exe.hds.tar.gz * Upload the image to glance: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/newton/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 = vz:///system
* Remove 'cpu_mode' parameter or set the following:
cpu_mode = none
* 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
...
[vstorage-ploop]
vzstorage_default_volume_format = ploop
vzstorage_shares_config = /etc/cinder/vzstorage-shares-vstorage.conf
volume_driver = cinder.volume.drivers.vzstorage.VZStorageDriver
volume_backend_name = vstorage-ploop
[vstorage-qcow2]
vzstorage_default_volume_format = qcow2
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"]
* Create two new volume types:
$ cinder type-create vstorage-qcow2
$ cinder type-key vstorage-qcow2 set volume_backend_name=vstorage-qcow2
$ 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-api
$ systemctl restart openstack-cinder-scheduler
$ 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
