• Running Laptop, server style, with the Lid closed.
  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.

• 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
  • qemu wiki: User documentation
  • qemu wiki: KVM
• 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
  • Cockpit is a web-based graphical interface for servers, intended for everyone.

• How To Forward a Port.
  • A port forward is a way of making a computer on your home or business network accessible to computers on the internet, even though they are behind a router or firewall. It is commonly used in gaming, security cameras, home automation, and the Internet of Things (IoT). Port forwards are setup in your router. A forwarded port is also known as open. After you have forwarded a port you have an open port.
