 OpenStack is the software suite used on the Compute Canada Cloud to control hardware resources such as computers, storage and networking. It allows the creation and management of virtual machines ("VMs", or "instances"), which act like separate individual machines, by emulation in software. This allows users complete control over their computing environment, from choosing an operating system to software installation and configuration. Diverse use cases are supported, from hosting websites to creating virtual clusters. More documentation on OpenStack can be found at the [http://docs.openstack.org/ OpenStack web site].
-This page describes how to perform common tasks encountered while working with OpenStack. It is assumed that you have already read [[Cloud Quick Start]] and understand the basic operations of launching and connecting to a VM. Most tasks can be performed using the dashboard, as described there and below. But some require use of the command line tools, for example [[#Creating an Image From a Volume|creating an image]]. See [[OpenStack Command Line Clients]] for more information.

 =Security Groups=
 A security group is a set of rules to control network traffic into and out of your virtual machines. To manage security groups go to ''Project->Compute->Access & Security'' and select the ''Security Groups'' tab. You will see a list of currently defined security groups. If you have not previously defined any security groups, there will be single default security group.
-To add or remove rules from a security group click ''Manage Rules'' beside that group. To add a new rule click ''Add Rule'' button in the top right; to remove a rule click ''Delete Rule'' beside the rule you wish to delete.
+To add or remove rules from a security group, click Manage Rules beside that group. When the group description is displayed, you can add or remove rules by clicking the +Add Rule and Delete Rule buttons respectively.
 The '''default security group''' contains rules which allow a VM access out to the internet, for example to download operating system upgrades or package installations, but does not allow another machine to access it, except for other VMs belonging to the same default security group. We recommend you do not remove rules from the default security group as this may cause problems when creating new VMs. You may recall, however, in the [[Cloud Quick Start]] you were directed to add a security rule for port 22 to allow incoming traffic so that you were able to connect to your VM ([[Cloud Quick Start#Firewall, add rules to allow SSH|Firewall, add rules to allow SSH]]).
