Editor to share with you how to manage the virtual machine in Red Hat Enterprise Linux 5.4.I believe that most people do not know much about it, so share this article for your reference. I hope you will learn a lot after reading this article. Let's learn about it.

Using the virtual machine management tools virt-manager and virsh to manage virtual machines in Red Hat Enterprise Linux 5.4 is easier to control the kernel-based virtual machine environment.

Red Hat Enterprise Linux 5.4 is a * enterprise Linux version that supports KVM natively. In the * * part of this series, I showed you how to set up Red Hat Enterprise Linux 5.4 as the KVM host. The second part describes how to create a virtual machine in the host. In part 3, Sander van Vugt, a special virtualization expert from TechTarget China, will discuss the use of virt-manager and virsh to manage virtual machines.

To learn about the virtual machine management tools in Red Hat Enterprise Linux 5.4, first take a look at libvirt, a virtualization directory that allows virtual machine management on the host platform, even if the virtual machine is in a KVM environment or hosted on Xen hypervisor.

There are two virtual machine management tools related to libvirt: the graphics tool virt-manager and the command line tool virsh. However, the purposes of these two virtual machine management tools are completely different. Virt-manager as a graphical interface makes it easier to manage virtual machines, while virsh gives users complete control of virtual machines.

Use virt-manager to manage virtual machines

Because virt-manager makes it easier to manage virtual machines, it has limited management behavior settings-most of which are related to virtual machine operational status and hardware management.

Virt-manager management tasks are provided in the following three tables:

The Console table grants access to the virtual machine console and allows the user to work directly on the virtual machine.

The Overview table allows users to monitor the current virtual machine operation status and resource utilization.

The hardware table controls the virtual machine hardware settings. Options include virtual machine memory and storage allocation, as well as changing network settings.

There are three buttons on the table to manage the operational status of the virtual machine. Here, the administrator can start, stop, or pause the machine. Similarly, if you configure the KVM environment for virtual machine hot migration, you can access this option from the Virtual Machine > Migrate menu.

Use virsh to perform advanced management tasks

Using virsh to manage virtual machines is completely different. As mentioned earlier, virsh manages each virtual machine function through main commands and subcommands. To see all the commands, type virsh help. You may find a large number of commands, but each command has a help guide, just type virsh help. With virsh help uri, for example, you can see all the help on the virsh uri command.
