virsh показывает работающую виртуальную машину, но она не запускается или не имеет доступа к сети

У меня есть проверка времени, когда виртуальные машины работают на 18.04 (сервер) LTS. Я говорю "работает", потому что он чувствует, будто virsh сообщает, что работает, но никогда не запускается. Это очень базовая тестовая виртуальная машина, которую я пытаюсь настроить так, чтобы я мог получить правильный синтаксис для своих производственных пар (домашний сервер) виртуальных машин, которые я пытаюсь настроить. Я хочу выйти и вернуться к 14.04 LTS, как это было много лет назад, но я пытаюсь понять, ПОЧЕМУ я вижу то, что я есть.

Это FRESH установка сервера Ubuntu 18.04 LTS, и до сих пор сделано только следующее.

добавьте в /etc/apt/sources.list, это предотвратит обнаружение и установку пакетов операционной системой, в частности mailutils & ubuntu-vm-builder.

deb http://archive.ubuntu.com/ubuntu/ bionic universe
deb http://archive.ubuntu.com/ubuntu/ bionic-updates universe

sudo apt-get install zfsutils-linux
sudo zpool import Storage
sudo zpool status
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install htop nmon samba nfs-kernel-server nfs-common qemu-kvm postfix mailutils ubuntu-vm-builder libvirt-bin

отключить дискету:

echo "blacklist floppy" | sudo tee /etc/modprobe.d/blacklist-floppy.conf
sudo rmmod floppy
sudo update-initramfs -u

Вот вывод /etc/netplan/50-cloud-init.yaml: (Я не знаю об этом, у меня НЕ установлен экземпляр облака, поэтому, возможно, есть проблема с фактической установкой 18.04 LTS, потому что все учетные записи, которые я видел в этом, указывают, что это ЯВЛЯЕТСЯ установлена ​​другая версия, чем я ожидаю

network:
    version: 2
    renderer: networkd
    ethernets:
            switchports:
              # all cards on second PCI bus; unconfigured by themselves, will be added
              # to br0 below
              match:
                name: enp1*
              mtu: 4400
    bridges:
      # the key name is the name for virtual (created) interfaces; no match: and
      # set-name: allowed
      br0:
        # IDs of the components; switchports expands into multiple interfaces
        interfaces: [switchports]
        addresses: [172.16.5.20/24]
        gateway4: 172.16.5.1
        nameservers:
          addresses: [172.16.5.2]
        parameters:
          forward-delay: 0
          stp: false

sudo netplan apply

Как вы можете видеть, мост 0 исправен и может подключаться к Интернету, без проблем подключаться к ssh.

br0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 172.16.5.20  netmask 255.255.255.0  broadcast 172.16.5.255

Ниже приведен вывод команды, используемой для раскрутки виртуальной машины. Я немного запутался в увиденных ошибках, так как они показываются как информационные, и не останавливают настройку. Когда я пытаюсь пинговать, я получаю только "dest host unreachable".
