Libvirt: não há como usar um ônibus isa?

1

Eu encontrei uma maneira de executar o Windows95 (estou um pouco nostálgico e uso sistemas antigos para testes) com o qemu

 /usr/bin/qemu-system-i386  -L pc-bios -m 64 -hda /home/user/.local/libvirt/images/win95.img  -net nic,model=ne2k_isa -net user -soundhw sb16 --enable-kvm -cpu qemu32 -M isapc

Com esta linha funciona bem, execute com baixo uso de cpu.

Quero agora importar no libvirt

Eu crio o arquivo .args

LC_ALL=C 
PATH=/bin:/usr/bin:/sbin:/usr/sbin
HOME=/home/user
USER=user
LOGNAME=user qemu-system-i386  -L pc-bios -M isapc -m 64 -hda win95.img -net nic,model=ne2k_isa -net user -soundhw sb16 --enable-kvm -cpu qemu32

Converter ...

virsh domxml-from-native qemu-argv file.args  > win95.xml

Mas quando tento correr ...

virsh create win95.xml

error: Failed to create domain from win95.xml
error: XML error: No PCI buses available

Este é o arquivo xml: nenhuma maneira de obter isa na libvirt?
