GETTING XCP-NG ONLINE
XCP-ng is an open-source Linux distribution based on the Xen Project, providing a high-performance virtualization platform with a pre-configured Xen Hypervisor and Xen API project (XAPI) out-of-the-box. It was created as a community-driven successor to Citrix XenServer, offering a secure and centralized management console for virtualization workloads, and is compatible with tools like Packer, Terraform, and Ansible2. XCP-ng aims to be a fully integrated virtualization solution that can run on bare-metal servers without requiring deep Linux knowledge.
The latest version of XCP-ng is 8.3, released on October 7, 2024. This version is part of the 8.x platform and is considered a standard release, meaning it includes the newest features and enhancements. XCP-ng 8.3 is designed to provide improved performance and support for the latest hardware. It also benefits from a more rigorous testing process to ensure stability. Over time, XCP-ng 8.3 will transition to a Long-Term Support (LTS) release, where it will receive only bug fixes and security patches.
Installing xcp-ng
To install XCP-ng, you begin by visiting the XCP-ng website to download the latest ISO file. With the ISO file in hand, you need to create a bootable USB drive using a tool like Rufus on Windows or the dd command on Linux. Once the bootable USB drive is prepared, insert it into the server and set the BIOS or UEFI to boot from the USB drive. After the server boots from the USB, select your preferred language and accept the license agreement to proceed.
Next, you'll choose the disk for installation, confirming any warnings about data erasure. You'll then select a primary storage repository for your virtual machines. Following that, configure your host by setting a secure password, configuring the network settings, and setting the hostname and DNS resolvers. After setting the timezone and optionally configuring an NTP server for time synchronization, review the installation summary and confirm the settings. Start the installation process and once it is complete, remove the USB drive and reboot the server. Finally, access your XCP-ng host from another machine using XCP-ng Center or Xen Orchestra to complete the setup and start managing your virtual environment.
- Download the ISO: First, navigate to the officialXCP-ng websiteand download the latest version of the XCP-ng ISO file. This file contains the entire operating system and necessary components to install XCP-ng on your server. Make sure to choose the right version that suits your hardware and requirements.
- Create Bootable Media: Use a tool like Rufus (for Windows) or the
ddcommand (for Linux) to create a bootable USB drive from the downloaded ISO file. This step is crucial as it prepares the USB drive to be used as the installation medium for XCP-ng. Ensure you select the correct USB drive to avoid accidentally overwriting important data on other drives. - Boot from USB: Insert the bootable USB drive into the target server and boot from it. To do this, you might need to access the BIOS/UEFI settings of your server (usually by pressing a key like F2, F12, Delete, or Esc during startup) and set the USB drive as the first boot device. This will allow the server to boot from the USB drive and start the XCP-ng installer.
- Language Selection: Once the server boots from the USB drive, you'll be prompted to select a language for the installation process. Choose your preferred language and press Enter. This sets the language for the installation interface and ensures you can follow the prompts in a language you are comfortable with.
- License Agreement: Read and accept the license agreement to proceed with the installation. This step ensures that you agree to the terms and conditions of using XCP-ng. Failure to accept the license agreement will halt the installation process.
- Disk Selection: Select the disk where you want to install XCP-ng. The installer will display a list of available disks. Choose the appropriate disk and confirm any warnings about data being erased on the selected disk. This step is crucial as it determines where XCP-ng will be installed and any existing data on the selected disk will be lost.
- Storage Repository: Choose a primary storage repository for your virtual machines. This repository will be used to store the virtual disks of your VMs. You can configure additional storage repositories later if needed. This step is important for managing the storage of your virtual infrastructure effectively.
- Host Password: Set a secure password for the root user. This password will be used to manage the XCP-ng host. Enter the password twice to confirm and ensure it is strong and secure to protect your system from unauthorized access.
- Networking: Configure the network settings for your host. You can choose to use DHCP to automatically obtain an IP address or set a static IP address manually. If using a static IP, provide the IP address, subnet mask, gateway, and DNS servers. Proper network configuration is essential for the host to communicate with other devices on the network.
- Hostname and DNS: Set the hostname for your XCP-ng host. This can be a fully qualified domain name (FQDN) or a simple hostname. Confirm or modify the DNS resolvers if needed. Setting a hostname helps identify the host on the network and ensures proper DNS resolution.
- Installation Confirmation: Review the installation summary and confirm all settings are correct. If everything looks good, start the installation process by selecting "Install". This step initiates the actual installation of XCP-ng on the selected disk and configures it according to the settings you provided.
- Reboot: Once the installation is complete, remove the USB drive and reboot the server. The system will boot into XCP-ng, and you'll be able to access the management console. This step finalizes the installation and prepares the host for further configuration and management.
- Post-Installation: After rebooting, access your XCP-ng host from another machine using XCP-ng Center or Xen Orchestra. Follow the on-screen instructions to complete the initial setup and start managing your virtual environment. This step involves configuring additional settings, creating virtual machines, and managing your virtual infrastructure using the XCP-ng management tools.
