    1. Edit logind.conf sudo vim /etc/systemd/logind.conf.
    2. Remove the # from these lines then set values to ignore:
      • HandleSuspendkey=ignore
      • HandleLidSwitch=ignore
      • HandleLidSwitchDocked=ignore
    3. Save then quit.
      • I'm not going to tell you how ;)
    4. Finally, restart systemd-logind.
      • sudo systemctl restart systemd-logind.service

Way of the Archer72.

Way of the SGOTI.

  • RHEL Documentation: Creating guests with virt-install
    • RHEL 9 product documentation list
    • You can use the virt-install command to create virtual machines and install operating system on those virtual machines from the command line. virt-install can be used either interactively or as part of a script to automate the creation of virtual machines.
  • virt-manager
    • The virt-manager application is a desktop user interface for managing virtual machines through libvirt. It primarily targets KVM VMs, but also manages Xen and LXC (linux containers).
    • virt-install is a command line tool which provides an easy way to provision operating systems into virtual machines.
    • virt-viewer is a lightweight UI interface for interacting with the graphical display of virtualized guest OS. It can display VNC or SPICE, and uses libvirt to lookup the graphical connection details.
    • virt-clone is a command line tool for cloning existing inactive guests. It copies the disk images, and defines a config with new name, UUID and MAC address pointing to the copied disks.
    • virt-xml is a command line tool for easily editing libvirt domain XML using virt-install’s command line options.
    • virt-bootstrap is a command line tool providing an easy way to setup the root file system for libvirt-based containers.
  • qemu documentation
  • KVM homepage
    • KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). It consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko.
    • Using KVM, one can run multiple virtual machines running unmodified Linux or Windows images. Each virtual machine has private virtualized hardware: a network card, disk, graphics adapter, etc.
  • Cockpit
  • Youtube video: Fedora server on a Laptop.
    • 14:45, editing /etc/systemd/logind.conf
  • Youtube video: Deploying Nextcloud AIO containers.
