# Description Cockpit is a web-based management utility that gives users a web interface to manage their servers. Using the `cockpit-machines` plugin, you can use Cockpit to manage virtual machines as well. In this lesson, we will walk through creating a new virtual machine with Cockpit, including installing a 'minimal' CentOS 8 instance. #### Reference Links [CentOS Mirrors List](http://isoredirect.centos.org/centos/8/isos/x86_64/) ### Creating a Virtual Machine Using Cockpit #### Get the CentOS 8 Boot ISO We will need a CentOS 8 Boot ISO for installation 1. Download the latest **CentOS 8 Boot ISO** (...-boot.iso) from the mirror list above. 2. Save or copy it to `/tmp` on your system. #### Log in to Cockpit Log in to the Cockpit web interface at `http://<YOUR_HOST_IP>:9090` #### Add the `/home/Virtual_Machines` directory to the Storage Pools 1. In the upper-right hand corner of the 'Virtual Machines' pane, you will see the link to the **Storage Pools**. Click on this link. 2. In the upper right-hand corner of the 'Storage Pools' pane, you will see a button labeled *Create Storage Pool*. Click it. **Settings:** - *Connection:* QEMU/KVM System connection - *Name:* `Virtual_Machines` - *Type:* Filesystem Directory - *Target Path:* `/home/Virtual_Machines` - *Startup:* CHECKED 3. Click **Create**. You should see your new `Virtual_Machines` storage pool. Click on the **Virtual Machines** link in the upper left-hand corner of the pane to go back to the *Virtual Machines* pane. #### Create a New Virtual Machine 1. In the upper right-hand corner of the *Virtual Machines* pane, click on the **Create VM** button. 2. We're going to use the following values for the new VM: - Connection: QEMU/KVM System connection - Name: centos-8-cockpit-vm - Installation Source Type: Local Install Media - Installation Source: /tmp/CentOS... (exact file name will depend on your download) - Storage: No Storage (we will add this later as we are not using the default location) - Memory: Set this to an appropriate value for your system - OS Vendor: CentOS - Operating System: CentOS 7.0 - Immediately Start VM: UNCHECKED 3. Click on the **Create** button. The **Create New Virtual Machine** window will disappear, and you will be back in the *Virtual Machines* pane. #### Add a Virtual Disk 1. Click on the entry for the new `centos-8-cockpit-vm`. Click on the **Disks** tab. Click on the **Add Disk** button on the right. 2. Set the Add Disk` Settings: - *Source:* Create New - *Pool:* `Virtual_Machines` - *Name:* `centos-8-cockpit-vm` - *Size:* Set this to an appropriate value for your system - *Format:* `qcow2` - *Show Performance Options:* LEAVE DEFAULT(S) 3. Click on **Add**. #### Launch the CentOS 8 Installation 1. Click on the **Consoles** tab, then click on the **Install** button on the right-hand side. This will launch the installation. Click in the console window to enable input. 2. We're going to perform a 'Minimal' CentOS 8 installation. Once the installation is complete, click on the **Reboot** button in the installer. This will shut down the VM. #### Start the New VM 1. Now that installation is complete, and the VM is shut down, we can click on **Run** on the right-hand side and start the new VM. 2. Once the VM is up and running, click on the console window and log in as `cloud_user`. Let's patch the system if required: ``` sudo dnf -y update ``` 3. Shut down the VM: ``` sudo systemctl poweroff ``` Congratulations on creating your first VM with Cockpit! ### In this lesson, we covered: - Logging in to Cockpit - Adding the `Virtual_Machines` directory to the storage pools - Creating a new virtual machine - Installing CentOS 8 “Minimal” - Patching the new VM
