  • Setup libvirtd on the physical host (CentOS Stream release 9) so we can create a Ubuntu VM<\/li>\n<\/ul>\n\n\n\n
      \n
    1. Check Hardware Virtualization
      $ grep -e ‘vmx’ -e ‘svm’ \/proc\/cpuinfo<\/li>\n\n\n\n
    2. Install Virtualization Packages
      $ sudo dnf install -y qemu-kvm libvirt virt-manager virt-install virt-viewer virt-top bridge-utils libguestfs-tools<\/li>\n\n\n\n
    3. Start and Enable libvirtd
      $ sudo systemctl enable –now libvirtd
      $ sudo systemctl status libvirtd<\/li>\n\n\n\n
    4. Configure User Permissions
      $ sudo usermod -aG libvirt $USER
      $ sudo usermod -aG kvm $USER
      $ newgrp libvirt<\/li>\n\n\n\n
    5. Start the Default Network
      $ sudo virsh net-start default
      $ sudo virsh net-autostart default<\/li>\n\n\n\n
    6. Enable ordinary user to create a VM and have it have networking without using sudo
      $ ip a #(find your bridge interface e.g., virbr0)
      $ sudo mkdir -p \/etc\/qemu
      $ echo “allow virbr0” | sudo tee \/etc\/qemu\/bridge.conf
      $ sudo chmod 644 \/etc\/qemu\/bridge.conf
      $ sudo chmod u+s \/usr\/libexec\/qemu-bridge-helper<\/li>\n<\/ol>\n\n\n\n

      During the Windows 10 installation in the VM, Activation may fail with “Something went wrong: But you can try again”. OOBELOCAL – likely due to Windows not recognizing the NIC
      Solution:
      – On the error screen, Use the New Local Account Command: Press Shift + F10 (or Fn + Shift + F10) on the Microsoft account screen to open the Command Prompt. 
      – Click on the black Command Prompt window to make sure it is active. 
      – Type start ms-cxh:localonly and press Enter. 
      – This opens the local account setup prompt so you can create a offline username. <\/p>\n\n\n\n
