Part V Managing virtual machines with QEMU

  • 32 QEMU overview
  • QEMU is a fast, cross-platform open source machine emulator which can emulate many hardware architectures. QEMU lets you run a complete unmodified operating system (VM Guest) on top of your existing system (VM Host Server). You can also use QEMU for debugging purposes—you can easily stop your runnin…

  • 33 Setting up a KVM VM Host Server
  • This section documents how to set up and use SUSE Linux Enterprise Server 15 SP4 as a QEMU-KVM based virtual machine host.

  • 34 Guest installation
  • The libvirt-based tools such as virt-manager and virt-install offer convenient interfaces to set up and manage virtual machines. They act as a kind of wrapper for the qemu-system-ARCHcommand. However, it is also possible to use qemu-system-ARCH directly without using libvirt-based tools.

  • 35 Running virtual machines with qemu-system-ARCH
  • Once you have a virtual disk image ready (for more information on disk images, see Section 34.2, “Managing disk images with qemu-img”), it is time to start the related virtual machine. Section 34.1, “Basic installation with qemu-system-ARCH” introduced simple commands to install and run a VM Guest. …

  • 36 Virtual machine administration using QEMU monitor
  • When a virtual machine is invoked by the qemu-system-ARCH command, for example qemu-system-x86_64, a monitor console is provided for performing interaction with the user. Using the commands available in the monitor console, it is possible to inspect the running operating system, change removable med…
