The administration of those components can be managed through the web-based interface or with the help of OpenStack command line.<\/p>\n\n\n\n<p>In this tutorial, we will be showing how to setup a fully functional all-in-one openstack node for your cloud infra.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/blog.pheonixsolutions.com\/wp-content\/uploads\/2019\/05\/OpenStack\u00ae_Logo_2016.svg_-1024x495.png\" alt=\"\" class=\"wp-image-4640\" width=\"410\" height=\"198\" srcset=\"https:\/\/pheonixsolutions.com\/blog\/wp-content\/uploads\/2019\/05\/OpenStack\u00ae_Logo_2016.svg_-1024x495.png 1024w, https:\/\/pheonixsolutions.com\/blog\/wp-content\/uploads\/2019\/05\/OpenStack\u00ae_Logo_2016.svg_-300x145.png 300w, https:\/\/pheonixsolutions.com\/blog\/wp-content\/uploads\/2019\/05\/OpenStack\u00ae_Logo_2016.svg_-768x371.png 768w, https:\/\/pheonixsolutions.com\/blog\/wp-content\/uploads\/2019\/05\/OpenStack\u00ae_Logo_2016.svg_.png 1200w\" sizes=\"auto, (max-width: 410px) 100vw, 410px\" \/><\/figure><\/div>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/blog.pheonixsolutions.com\/wp-content\/uploads\/2019\/05\/install-centos-7-logo.png\" alt=\"\" class=\"wp-image-4641\" width=\"403\" height=\"211\" srcset=\"https:\/\/pheonixsolutions.com\/blog\/wp-content\/uploads\/2019\/05\/install-centos-7-logo.png 600w, https:\/\/pheonixsolutions.com\/blog\/wp-content\/uploads\/2019\/05\/install-centos-7-logo-300x158.png 300w\" sizes=\"auto, (max-width: 403px) 100vw, 403px\" \/><\/figure><\/div>\n\n\n\n<h4 class=\"wp-block-heading\">Prerequisites<\/h4>\n\n\n\n<ol class=\"wp-block-list\"><li>Cent OS 7.6 server with VT enabled in BIOS<\/li><li>SSH Access to server<\/li><li>Set server host name<\/li><li>Minimum of 16 GB of RAM<\/li><li>Processor with VT support<\/li><\/ol>\n\n\n\n<p>To verify VT support, please run the below command.  <em>As a result<\/em> you will see the numbers.<\/p>\n\n\n\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"generic\" data-enlighter-theme=\"\" data-enlighter-highlight=\"\" data-enlighter-linenumbers=\"\" data-enlighter-lineoffset=\"\" data-enlighter-title=\"\" data-enlighter-group=\"\"> egrep --color 'vmx|svm' \/proc\/cpuinfo | wc \u2013l\n16<\/pre>\n\n\n\n<p>Output: (The value should not be zero)<\/p>\n\n\n\n<p>Before we move to opestack installation.
