Comment 7 for bug 1317987

Hi
 I do get further with full pathnames for the kernel,initrd, and disk image; However there are issues with
the xml file that was generated from the args file:

(trusty)root@jade-rev4:/home2/qemu# cat go14.04.args
qemu-system-ppc -M ppce500 -nographic -kernel /home2/qemu/jade-kernel-2.0.bin -initrd /home2/qemu/jade-initrd-2.0.bin -m 1024 -enable-kvm -drive file=/home2/qemu/jade-ubuntu-14.04.qcow2.netinstall,if=virtio -append "console=ttyS0" -no-shutdown -no-reboot -name Ubuntu-VM01

(trusty)root@jade-rev4:/home2/qemu#

virsh domxml-from-native qemu-argv go14.04.args > vm01.xml

(trusty)root@jade-rev4:/home2/qemu# virsh -c qemu:///system

What is the root cause of the PCI config error ?
