→Installing OpenStack with help of packstack on Virtuozzo 7 (*Production Setup*)
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:
virt_type = parallels
images_type = qcow2
connection_uri = parallelsvz:///system
Delete the line:
* Create a new repo fileInstall Virtuozzo Platform Release package to all Virtuozzo OpenStack nodes:
* Install packstack package:
* Download sample Vz7 packstack answer file:
$ wget https://raw.githubusercontent.com/virtuozzo/virtuozzo-openstack-scripts/master/vz7-packstack-sampleocata.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
* Then run packstack:
$ packstack --answer-file =vz7-packstack-sampleocata.txt

* Follow instructions on [http://docs.openstack.org/newton/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]
NOTE: this image was created for testing purposes only. Don't use it in production as is!

== 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:
[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:
<!--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:
* Authenticate your Virtuozzo Storage client nodes in oreser to allow them to mount cluster:
$ echo $CLUSTER_PASSWD | vstorage auth-node -c cc YOUR-CLUSTER-NAME -P
* Then restart cinder services:
$ systemctl restart openstack-cinder-volume
== How to create a new image 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
$ 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
$ prlctl exec glance-$ct sed -i '/- growpart/d' /vz/root/$uuid/etc/cloud/cloud.cfg $ prlctl exec glance-$ct sed -i '/- resizefs/d' /vz/root/$uuid/etc/cloud/cloud.cfg
* Prepare network scripts
cat > /vz/root/$uuid/etc/sysconfig/network-scripts/ifcfg-eth0 << _EOF
DEVICE=eth0
ONBOOT=yes
_EOF
* If you need more than one network adapters withing within a container, make as many copies as you need
$ prlctl exec glance-cp /vz/root/$ct cp uuid/etc/sysconfig/network-scripts/ifcfg-eth0 /vz/root/$uuid/etc/sysconfig/network-scripts/ifcfg-eth1 $ prlctl exec glance-$ct sed -i '/eth0/eth1' /vz/root/$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 * Stop the container $ prlctl stop glance-$ct
* Create ploop disk and copy files
$ mkdir /tmp/ploop-$ct/dst
$ ploop mount -m /tmp/ploop-$ct/dst /tmp/ploop-$ct/DiskDescriptor.xml
$ prlctl umount glance-$ct
* Now the image tmp/ploop-$ct/$ct.hds is ready to be uploaded to Glance
