Editing Setup OpenStack with Virtuozzo 7

{{Virtuozzo}}

This howto describes steps by step installation of OpenStack devstack with [[Virtuozzo]] 7.

Execute the following commands within you Virtuozzo 7 host as root:

Install RDO repo:

 $ yum install -y https://rdoproject.org/repos/rdo-release.rpm

Install EPEL repo:
 
 $ yum install -y epel-release

Install required packages:
 $ yum install -y git patch redhat-lsb-core euca2ools mysql-connector-python scsi-target-utils

Reinstall http and mod_wsgi:

 $ yum remove -y httpd httpd-tools mod_wsgi
 $ yum install -y httpd

Enable IP connection tracking for CT0:

 $ echo -ne "options nf_conntrack ip_conntrack_disable_ve0=0\n" > /etc/modprobe.d/vz.conf
 $ echo -ne "options nf_conntrack ip_conntrack_disable_ve0=0\n" > /etc/modprobe.d/parallels.conf

Then reboot your system:

 $ reboot

Create user "stack" and add him to sudoers:

 $ adduser stack -d /vz/stack
 $ chmod 755 /vz/stack
 $ echo "stack ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers

Download and unpack container image:

 $ su stack -c "cd ~ && wget http://updates.virtuozzo.com/server/virtuozzo/en_us/odin/7/techpreview-ct/centos7-exe.hds.tar.gz"
 $ su stack -c "cd ~ && tar -xzvf centos7-exe.hds.tar.gz"

Clone devstack:
 
 $ su stack -c "cd ~ && git clone git://git.openstack.org/openstack-dev/devstack"

Create local.conf file:

 $ cat > ~stack/devstack/local.conf << _EOF
 <nowiki>[[local|localrc]]</nowiki>

 HOST_IP=1.1.1.1
 MYSQL_PASSWORD=password

 _EOF

Change HOST_IP within created ~stack/devstack/local.conf to a valid IP address of your Virtuozzo 7 host.
Change password for OpenStack services to whatever you prefer in ~stack/devstack/local.conf.
Make libvirt daemon accessible via socket for stack user:

 $ sed -i s/"#unix_sock_group = \"libvirt\""/"unix_sock_group = \"stack\""/ /etc/libvirt/libvirtd.conf
 $ sed -i s/"#unix_sock_ro_perms = \"0777\""/"unix_sock_ro_perms = \"0777\""/ /etc/libvirt/libvirtd.conf
 $ sed -i s/"#unix_sock_rw_perms = \"0770\""/"unix_sock_rw_perms = \"0770\""/ /etc/libvirt/libvirtd.conf
 $ sed -i s/"#unix_sock_dir = \"\/var\/run\/libvirt\""/"unix_sock_dir = \"\/var\/run\/libvirt\""/ /etc/libvirt/libvirtd.conf
 $ sed -i s/"#auth_unix_ro = \"none\""/"auth_unix_ro = \"none\""/ /etc/libvirt/libvirtd.conf
 $ sed -i s/"#auth_unix_rw = \"none\""/"auth_unix_rw = \"none\""/ /etc/libvirt/libvirtd.conf

Clone nova repository:

 $ su stack -c "cd ~ && git clone git://git.openstack.org/openstack/nova"

Make libvirt 1.2.8 be minimum required version to run with Virtuozzo:

 $ sed -i -e "s/MIN_LIBVIRT_PARALLELS_VERSION = (1, 2, 12)/MIN_LIBVIRT_PARALLELS_VERSION = (1, 2, 8)/"  ~stack/nova/nova/virt/libvirt/driver.py

Start devstack:

 $ su stack -c "~/devstack/stack.sh"

After script finishes, setup your iptables rules to allow incoming http trafic if you want to use OpenStack dashboard. For instance:

 $ iptables -D INPUT -j REJECT --reject-with icmp-host-prohibited
 $ iptables -A INPUT -p tcp --dport http -j ACCEPT
 $ iptables -A INPUT -j REJECT

Here you are!
