We will be using the following steps to install the VSM software:

  1. Before proceeding with VSM installation, let us upgrade all four VMs to the latest CentOS 7 packages and configuration:
        $ sudo yum update -y        $ sudo reboot
  1. Log in to all four VSM VMs and configure Ceph Jewel version repositories:
        sudo yum install -y http://download.ceph.com/rpm-jewel/el7/noarch/                            ceph-release-1-1.el7.noarch.rpm
  1. In this demonstration, we will use CentOS 7 as the base operating system; let's download the VSM repository for CentOS 7. Log in to the vsm-controller node as cephuser and get the VSM version 2.2.0:
        ssh cephuser@192.168.123.100        $ wget https://github.com/01org/virtual-storage- manager/releases/download/v2.2.0/2.2.0-521-centos7.tar.gz ...
