Part II Managing virtual machines with libvirt

  • 8 libvirt daemons
  • A libvirt deployment for accessing KVM or Xen requires one or more daemons to be installed and active on the host. libvirt provides two daemon deployment options: monolithic or modular daemons. libvirt has always provided the single monolithic daemon libvirtd. It includes the primary hypervisor driv…

  • 9 Preparing the VM Host Server
  • Before you can install guest virtual machines, you need to prepare the VM Host Server to provide the guests with the resources that they need for their operation. Specifically, you need to configure:

  • 10 Guest installation
  • A VM Guest consists 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. For a l…

  • 11 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.

  • 12 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.

  • 13 Advanced storage topics
  • This chapter introduces advanced topics about manipulating storage from the perspective of the VM Host Server.

  • 14 Configuring virtual machines with Virtual Machine Manager
  • 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 Show virtual hardware details in the toolbar.

  • 15 Configuring virtual machines with virsh
  • You can use virsh to configure virtual machines (VM) on the command line as an alternative to using the Virtual Machine Manager. With virsh, you can control the state of a VM, edit the configuration of a VM or even migrate a VM to another host. The following sections describe how to manage VMs by using virsh.

  • 16 Enhancing virtual machine security with AMD SEV-SNP
  • You can enhance the security of your virtual machines with AMD Secure Encrypted Virtualization-Secure Nested Paging (SEV-SNP). The AMD SEV-SNP feature isolates virtual machines from the host system and other VMs, protecting the data and code. This feature encrypts data and ensures that all changes with the code and data in the VM are detected or tracked. Since this isolates VMs, the other VMs or the host machine are not affected with threats.

    This section explains the steps to enable and use AMD SEV-SNP on your AMD EPYC server with SUSE Linux Enterprise Server 15 SP6.

  • 17 Migrating VM Guests
  • One of the major advantages of virtualization is that VM Guests are portable. When a VM Host Server needs maintenance, or when the host becomes overloaded, the guests can be moved to another VM Host Server. KVM and Xen even support live migrations during which the VM Guest is constantly available.

  • 18 Xen to KVM migration guide
  • As the KVM virtualization solution is becoming more and more popular among server administrators, many of them need a path to migrate their existing Xen based environments to KVM. As of now, there are no mature tools to automatically convert Xen VMs to KVM. There is, however, a technical solution th…
