Part II Managing Virtual Machines with libvirt

8 Starting and Stopping libvirtd

The communication between the virtualization solutions (KVM, Xen, LXC) and the libvirt API is managed by the daemon libvirtd, which needs to run on the VM Host Server. libvirt client applications such as virt-manager, possibly running on a remote machine, communicate with libvirtd running on the VM …

9 Guest Installation

A VM Guest is comprised of an image containing an operating system and data files and a configuration file describing the VM Guest's virtual hardware resources. VM Guests are hosted on and controlled by the VM Host Server. This section provides generalized instructions for installing a VM Guest.

10 Basic VM Guest Management

Most management tasks, such as starting or stopping a VM Guest, can either be done using the graphical application Virtual Machine Manager or on the command line using virsh. Connecting to the graphical console via VNC is only possible from a graphical user interface.

11 Connecting and Authorizing

Managing several VM Host Servers, each hosting multiple VM Guests, quickly becomes difficult. One benefit of libvirt is the ability to connect to several VM Host Servers at once, providing a single interface to manage all VM Guests and to connect to their graphical console.

12 Managing Storage

When managing a VM Guest on the VM Host Server itself, it is possible to access the complete file system of the VM Host Server to attach or create virtual hard disks or to attach existing images to the VM Guest. However, this is not possible when managing VM Guests from a remote host. For this reaso…

13 Managing Networks

This chapter introduces common networking configurations supported by libvirt. It does not depend on the hypervisor used, which means that it is valid for all hypervisors supported by libvirt, such as KVM or Xen. These setups can be achieved using both the graphical interface of Virtual Machine Manager and the command line tool virsh.

14 Configuring Virtual Machines

Virtual Machine Manager's Details view offers in-depth information about the VM Guest's complete configuration and hardware equipment. Using this view, you can also change the guest configuration or add and modify virtual hardware. To access this view, open the guest's console in Virtual Machine Manager and either choose View › Details from the menu, or click the bulb icon in the toolbar.
