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
