Como uso o virt-install para criar uma instalação básica?

$ 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'

Eu preciso configurar a ponte?

Apenas o guia parece assumir que estou usando eth0 quando, na verdade, é wi-fi . Como isso muda /etc/network/interfaces ?

$ cat /etc/network/interfaces 
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
