→‎Installing OpenStack with help of packstack on Virtuozzo 7 (*Production Setup*)
* Create a new repo fileInstall Virtuozzo Platform Release package to all Virtuozzo OpenStack nodes:
cat > /etc/$ yum.repos.d/virtuozzoinstall vz-ocata.repo << _EOF [virtuozzoplatform-extra] name=Virtuozzo Extra baseurl=http://repo.virtuozzo.com/openstack/ocata/x86_64/os/ enabled=1 gpgcheck=1 priority=50 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-Virtuozzo-7 _EOFrelease
* Install packstack package:
* 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_CINDER_VSTORAGE_CLUSTER_NAMECONFIG_VSTORAGE_CLUSTER_NAME= 
# VStorage cluster password.
CONFIG_CINDER_VSTORAGE_CLUSTER_PASSWORDCONFIG_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-->
$ 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 mount glance-$ct $ id=$(vzlist glance-$ct | awk ' NR>1 { print $1 }') $ cp -Pr --preserve=all /vz/root/$iduuid/* /tmp/ploop-$ct/dst/ $ ploop umount -m /tmp/ploop-$ct/dst/ * Unmount the container 
$ prlctl umount glance-$ct
$ ploop umount -m /tmp/ploop-$ct/dst/
* Now the image tmp/ploop-$ct/$ct.hds is ready to be uploaded to Glance
