How to create openstack worker node

The "official" instructions how to install openstack components are located here:

http://docs.openstack.org/cactus/openstack-compute/admin/content/installing-openstack-compute-on-rhel6.html

Unfortunately they are not very clear and miss some key points. Below is summary of our installation procedure.

First of all, let us install worker node.

wget http://yum.griddynamics.net/yum/cactus/openstack/openstack-repo-2011.2-1.el6.noarch.rpm
rpm -ivh openstack-repo-2011.2-1.el6.noarch.rpm
yum install libvirt
chkconfig libvirtd on
/etc/init.d/libvirtd start
yum install openstack-nova-compute openstack-nova-compute-config
service openstack-nova-compute start
