I. brief introduction

1 introduction to XenServer

1) XENSERVER is a full server virtualization platform launched by CITRIX.

2) the XenServer package contains everything you need to create and manage the deployment of virtual x86 computers running on Xen, an open source paravirtualized virtual machine manager close to native performance.

3) XenServer has been optimized for both Windows and Linux virtual servers.

4) XenServer runs directly on the server hardware without the need for the underlying operating system, so it is an efficient and scalable system.

5) XenServer works by extracting elements (such as hard drives, resources, and ports) from the physical machine and assigning them to virtual machines running on the physical machine.

6) A virtual machine (VM) is a computer made up entirely of software that can run its own operating system and applications, just like a physical machine.

7) VM operates very much like a physical machine and includes its own virtual (software-based) CPU, RAM, hard disk, and network interface card (NIC).

8) XenServer can be used to create VM, generate VM disk snapshots, and manage VM workloads.

2. The way to manage XenServer

You can manage the XenServer:XenCenter and XenServer command line interfaces (CLI) in two ways.

XenCenter is a graphical user interface based on Windows. XenCenter allows management of XenServer hosts, pools, and shared storage from Windows desktops, as well as deployment, management, and monitoring of VM.

Through the XenServer command line interface (CLI), you can use Linux-based xe commands to manage XenServer.

3. Features and functions of XENSERVER

3.1Features of XENSVER

Provide the best performance for XenApp and XenDesktop

XenServer provides best-in-class performance for applications and desktop virtualization.

Through tight integration into the Microsoft environment and including licensing of XenApp and XenDesktop, XenServer is an ideal platform for Citrix application virtualization and desktop virtualization.

Only XenServer provides a superior user experience with NVIDIA GRID vGPU and market-leading NVIDIA scalability, including support for Intel Virtual Graphics (GVT-g) and Linux graphical desktops.

It maximizes virtual machine density and performance while reducing infrastructure storage costs through in-memory read caching and IntelliCache.

Innovative platform security

XenServer regularly introduces innovative security features, such as XenServer Direct Inspect API, which represents a shift in the protection mode of virtual infrastructure.

These API transfer the protection of virtual machines to the host, leaving viruses and malware nowhere to hide in the guest operating system.

XenServer Direct Inspect API enables security vendor partner integration to provide "better than physical protection" protection against malicious activities through this true agentless solution.

Enterprise Virtualization

XenServer enables IT departments to consolidate and control a large number of data center servers, thus greatly improving the utilization of existing hardware resources.

With significant performance and capacity gains in the CPU kernel, host RAM, VM RAM, and virtual disks for each virtual machine.

With innovative features such as Storage XenMotion, Shared-Nothing Migration, Health Check, and integration with Microsoft Windows update services to automate Windows virtual machine driver updates, XenServer helps IT administrators maximize efficiency, eliminate planned outages, and minimize unplanned outages within their infrastructure.

4. The system requirements of XenCenter are as follows:

II. Virtualized installation

1. Environmental preparation

1.1. System environment

1.2. Build the environment

Log in to the citrix official website to download the free version of XenServer: https://www.citrix.com.cn/downloads/xenserver/ (you need to sign up for a Citrix account before downloading)

2. XenServer installation

Burn the XenServer image file into a boot CD or U disk, as each brand and model of the server boot method is different, this article does not explain, the installation is everyone according to their own server model Baidu search.

After booting the image, click the "Enter" key to enter the installation.

Choose the default "US" for keyboard layout.

Select "OK" here.

Just select "accept"

Select "OK" here

In this experiment, my host has only one hard disk. If the cluster will use XenDesktop later, you need to check the red step-①

Select the installation source. If you use a USB disk or CD-ROM installation, you can directly select the first "Local Media".

Our image is downloaded from the official website. You can skip the effect here.

Configure the XenServer server password

Select the network card that is used to manage the XenServer server

Configure static IP addr

Configure the hostname and DNS (our DNS server has not been built yet, so use Google's DNS server for the time being)

Select time zone and time synchronization method

Enter the NTP server address

After setting up the NTP server, click "Install XenServer" to install XenServer

Do not install other packages for the time being, select "No" here

When you are finished, just restart

After rebooting, enter the state shown in the following figure. We will introduce other functions in this interface later. XenServer01 has been installed. Please install XenServer02 in the same way. Again, do not elaborate too much.

Then install the client to log in!
