offer convenient interfaces to set up and manage virtual machines. They act as a kind of wrapper for theqemu-system-ARCH
command. However, it is also possible to useqemu-system-ARCH
directly without usinglibvirt
-based tools.- 31 Running Virtual Machines with qemu-system-ARCH
Once you have a virtual disk image ready (for more information on disk images, see Section 30.2, “Managing Disk Images with qemu-img”), it is time to start the related virtual machine. Section 30.1, “Basic Installation with qemu-system-ARCH” introduced simple commands to install and run a VM Guest. …
- 32 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 …
