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 SP3 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 QEMU is running, 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 media, take screenshots or audio grabs and control other aspects of the virtual …
