Please make sure that your ISP/Data center provider /Network provider has given you IP ranges for your external network along with gateway IP address. We need to add external network in our openstack project so that our instances/virtual machines may use this external network to send traffic out and receive traffic from internet. Since we have added an internal network, so our instances will be able to communicate with each other fine but so far they will not be able to communicate with outside world. Here is the very first screen you should see specify network name here and click “Next”. Browse to Compute > Network > Network option and click on “Create Network” to add a new internal network.
Once the image has been uploaded to Glance, next step is to create internal network for the private communication between virtual machines. img file then use “QCOW2” here and for images of other extensions, you will be able to find appropriate format type in the drop down menu.Ĭlick “Create Image”option at the bottom of this window and your cloud image will be uploaded to the Glance service now and should be available for use for your new virtual machines.

iso file, then choose “ISO” here, if you are using. Specify image name, description, in image location type the URL for the online location from where cloud image is hosted (in case of cirros, we used ), and in image format, choose the correct type of the image, if you are using. Following screen will be loaded, from here you can upload image/ISO of your choice to the Glance service. Please login your openstack setup’s horizon dashboard and browse to Project > Compute > Images and click “Create Image” option from here. For those unaware of Cirros, it is a tiny Linux distribution used solely for testing purposes only. For the demonstration purpose, we will use Cirros OS image here. Cloud images for all popular operating systems can be found easily from the internet. For example, if you want to use CentOS operating system for your instances/virtual machines, you need to upload CentOS cloud image/ISO to Glance first.
In order to boot and use virtual machines in openstack, we need to upload images/ISO for the operating systems to openstack Glance service. Glance is the image service for openstack. Lets review each of the above mentioned steps in details with proper screenshots for easier understanding. Setup a new Router and add both internal and external network to it Without wasting much time, lets get straight to the point of discussion, here are five steps to be performed in order to setup/create/add virtual machines in openstack.Ĥ. Openstack is the most convient way to quickly setup a production ready cloud infrastructure, all you need is a pool of hardware to act as storage, compute and network devices and simple installation of openstack can manage it to take your productivity to the highest level. All these steps can be done via command line too, but we will cover command line instructions in another article. We tested these steps on openstack Liberty and Kilo release.

Hello Friends, today we will discuss how to create virtual machines (known as “ instances” in openstack terminology) using Horizon Dashboard.
