virt-install基本インストールの作成にはどのように使用できますか？
$ cat kvm/install_example
virt-install \
--name AsteriskNOW \
--ram=2048 \
--vcpus=2 \
--disk pool=default,size=30,bus=virtio,format=qcow2 \
--cdrom /home/thufir/Downloads/AsteriskNow-1013-current-64.iso \
--network bridge=kvmbr0,model=virtio \
--graphics vnc,listen=0.0.0.0,password=Qwerty1234 \
--boot cdrom,hd,menu=on
$ ./kvm/install_example

Domain installation does not appear to have been successful.
If it was, you can restart your domain by running:
virsh --connect qemu:///system start AsteriskNOW
otherwise, please restart your installation.
$ virsh --connect qemu:///system start AsteriskNOW
error: failed to get domain 'AsteriskNOW'
error: Domain not found: no domain with matching name 'AsteriskNOW'

ガイドだけが私がそれを使用していると仮定しているようです。eth0実際wi-fi、これはどのように変わりますか/etc/network/interfaces？
$ cat /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

libvirtデーモンを再起動して問題を解決しました。
sudo systemctl restart libvirtd
最新のディストリビューションの場合はlibvirtを使用してください。
