Contents

Prerequisites

IP connection tracking should be enabled for CT0. Please do the following:

  1. Open the file /etc/modprobe.d/parallels.conf
  2. Change the line options nf_conntrack ip_conntrack_disable_ve0=1 to options nf_conntrack ip_conntrack_disable_ve0=0
  3. Reboot the system

Git must be installed on your Virtuozzo node: 

yum install git

Devstack all-in-one installation

Clone virtuozzo scripts: 

$ cd /vz
$ git clone https://github.com/virtuozzo/virtuozzo-openstack-scripts
$ cd virtuozzo-openstack-scripts

Run the script and follow instructions (if any): 

$ ./setup_devstack_vz7.sh YOUR_HOST_IP YOUR_PASSWORD

Devstack multi node installation

Clone virtuozzo scripts on your CONTROLLER node: 

$ cd /vz
$ git clone https://github.com/virtuozzo/virtuozzo-openstack-scripts
$ cd virtuozzo-openstack-scripts

Run the script on your CONTROLLER node and follow instructions (if any): 

$ ./setup_devstack_vz7.sh YOUR_HOST_IP YOUR_PASSWORD CONTROLLER

Clone virtuozzo scripts on your COMPUTE node: 

$ cd /vz
$ git clone https://github.com/virtuozzo/virtuozzo-openstack-scripts
$ cd virtuozzo-openstack-scripts

Run the script on your COMPUTE node and follow instructions (if any): 

$ ./setup_devstack_vz7_compute.sh YOUR_COMPUTE_HOST_IP YOUR_PASSWORD COMPUTE CONTROLLER_HOST_IP

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:

  1. cd /vz/virtuozzo-openstack-scripts
  2. git pull
  3. Run ./setup_devstack_vz7.sh with options you need.

Install and configure a nova controller node on Virtuozzo 7

  • Follow instructions on OpenStack.org
  • In addition to above instructions change /etc/nova/nova.conf:
[DEFAULT]
...
vnc_keymap =

[libvirt]
...
virt_type = parallels
images_type = ploop
  • 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
  • Restart glance-api service:
systemctl restart openstack-glance-api.service
  • Download the container 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 --container-format bare --property vm_mode=exe --file centos7-exe.hds
  • Restart nova services:
systemctl restart openstack-nova-api.service \
 openstack-nova-cert.service openstack-nova-consoleauth.service \
 openstack-nova-scheduler.service openstack-nova-conductor.service \
 openstack-nova-novncproxy.service

Install and configure a compute node on Virtuozzo 7

  • Follow instructions on OpenStack.org
  • In addition to above instructions change /etc/nova/nova.conf:
[DEFAULT]
...
vnc_keymap =
force_raw_images = False

[libvirt]
...
virt_type = parallels
images_type = ploop
connection_uri = parallels+unix:///system
inject_partition = -2
  • Then restart nova-compute service:
systemctl restart openstack-nova-compute.service
