我的理解是，我可以在 Ubuntu 22.04 上使用 LibVirt 和 QEMU，而无需使用 KVM。为了做到这一点，我使用以下命令：
#!/bin/bash
sudo apt-get -y update && sudo apt-get -y upgrade
sudo apt-get -y install qemu-system qemu-efi qemu-user qemu-utils libvirt-clients libvirt-daemon libvirt-daemon-system libvirt-daemon-driver-qemu
sudo mkdir /home/foo && sudo useradd -d /home/foo nomad
sudo usermod -a -G kvm,libvirt-qemu,libvirt foo
sudo mkdir -p /home/foo/libvirt/images
sudo mkdir -p /home/foo/libvirt/isos
sudo chown :kvm /home/foo/libvirt/images
sudo rmdir /var/lib/libvirt/images
sudo ln -s /home/foo/libvirt/images /var/lib/libvirt/images
sudo ln -s /home/foo/libvirt/isos /var/lib/libvirt/isos
sudo mkdir -p /home/foo/.config/libvirt
sudo cp -rv /etc/libvirt/libvirt.conf /home/nomad/.config/libvirt/
sudo chown foo: /home/foo/.config/libvirt/libvirt.conf
sed -i 's\#uri_default\uri_default\g' /home/foo/.config/libvirt/libvirt.conf
sed -i 's\#user = "root"\user = "foo"\g' /etc/libvirt/qemu.conf
sed -i 's\#group = "root"\group = "libvirt-qemu"\g' /etc/libvirt/qemu.conf
sudo systemctl start libvirtd
systemctl status libvirtd
脚本的最后一行告诉我：

我的问题是，如何使用 libvirtd 以使其不寻找 /dev/kvm。
