libvirt users - Apr 2013 - fail to convert qemu xml to args with libvirt-1.0.4: An error occurred, but the cause is unknown

Hi,

I used to convert qemu XML to args with libvirt-1.0.3.
But it failed to convert with libvirt-1.0.4.

# virsh domxml-to-native qemu-argv test.xml >test.sh
error: An error occurred, but the cause is unknown


Comparing the debug file as below:
1) lbvirt-1.0.3

How can I debug this cause unknown error?

Hi Daniel,

Just Ping.
Did you ever successfully convert QEMU xml file to argv on other platforms?

Best Regards,
Olivia
