Thanks for submitting this bug. Can you confirm whether
the qemu-system-ppc package is installed? Please show the
results of

 dpkg -l | grep qemu-system-ppc
 dpkg -l | grep openbios-ppc

Hi,

(trusty)root@jade-rev4:/home2/qemu# dpkg -l | egrep "qemu-system-pcc|openb"
ii netcat-openbsd 1.105-7ubuntu1 powerpc TCP/IP swiss army knife
ii openbios-ppc 1.1-1ubuntu1 all PowerPC Open Firmware
ii openbsd-inetd 0.20091229-2ubuntu3 powerpc OpenBSD Internet Superserver
(trusty)root@jade-rev4:/home2/qemu#

I can run a vm manually :

(trusty)root@jade-rev4:/home2/qemu# cat go3.sh
exec qemu-system-ppc -M ppce500 -nographic -kernel jade-kernel.bin \
                -initrd jade-initrd-2.0.bin -m 1G -enable-kvm -drive \
         file=jade-ubuntu-14.04.qcow2,if=virtio -append "console=ttyS0 syboot=break" \

Just to make sure, could you replace qemu-system-pcc with qemu-system-ppc? Since
you say below that you can run it I assume that'll show the right thing.

[[e-mail] (john-d-0)]

Here you go

(trusty)root@jade-rev4:/home2/qemu# dpkg -l | egrep "qemu-system-ppc|openbio"
ii openbios-ppc 1.1-1ubuntu1 all PowerPC Open Firmware
ii qemu-system-ppc 2.0.0~rc1+dfsg-0ubuntu3.1 powerpc QEMU full system emulation binaries (ppc)

[Serge Hallyn (serge-hallyn)]

thanks. If I take your vm1.xml and specify a full path, so

<emulator>/usr/bin/qemu-system-ppc</emulator>

then virsh define is happy. Please let us know if that still doesn't work for you.

[[e-mail] (john-d-0)]

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

What is the root cause of the PCI config error ?

[Serge Hallyn (serge-hallyn)]

You're still able to run the same vm by hand (as was the case in comment #3)?

What sort of host are you running on?

If you add '-L /usr/share/qemu', to your command line, does that help?

If instead of building your own kernel, you download a cdimage like http://cdimages.ubuntu.com/ubuntu-server/daily/current/utopic-server-powerpc.iso, and boot that, does that work for you?

[[e-mail] (john-d-0)]

Hi;
I'll try your other images listed - if they are e500pc kernels (FreeScale P4080 SOC ) ; Our boot kernel is unique so far and is only used for boot IPL ;

Isn't this product suppose to work as well as Intel qemu + kvm ?

 I appreciate your help ; but these issues are related to out of box behavior ;

The PowerPC qemu ; qtemu related tools are no where near as full feature and functional as x86 ;

[Serge Hallyn (serge-hallyn)]

I'm trying to determine (without the kernel and initrds to reproduce with) whether the issue is in upstream qemu or in libvirt. If you can still run qemu-system-ppc by hand just fine, then we need to figure out whether and why libvirt is doing something different so we can fix it.

[Serge Hallyn (serge-hallyn)]

I believe this is fixed in wily. Can anyone confirm?
