configurando rede no sistema operacional convidado no KVMtool

Question

Estou tentando executar o Ubuntu 16.04 no kvmTool. Eu estou usando o seguinte comando para executar a imagem do Ubuntu no guest:

sudo ./lkvm run -k ~/kvmtool/guest_linux_kernel/linux-4.13/arch/x86_64/boot/bzImage -m 448 -c 4 --network mode=user --disk ~/kvmtool/ubuntu_disk/ubuntuD.img -i ~/kvmtool/guest_linux_kernel/linux-4.13/initrd-4.13.0-41-generic.img  -p "root=/dev/vda1"'

Falha ao configurar o dispositivo de rede corretamente. Aqui está a saída de lkvm run: link

Informações de rede:

ifconfig -a

sudo cat /etc/network/interfaces

# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

A imagem do disco funciona bem quando carregada com o Qemu.

Como posso habilitar interfaces de rede do Ubuntu usando o kvmtool?
