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

[Yin Olivia-R63875]

Hi Daniel,

I also tried libvirt-1.0.4 on my X86 machine.

user at x86:~ $ uname -a
Linux 2.6.32-33-server #70-Ubuntu SMP Thu Jul 7 22:28:30 UTC 2011 x86_64 GNU/Linux

user at x86:~ $ which virsh
/usr/local/bin/virsh
user at x86:~ $ /usr/local/bin/virsh --version
1.0.4

user at x86:~ $ cd libvirt-1.0.4/tests/qemuxml2argvdata 
user at x86:~/libvirt-1.0.4/tests/qemuxml2argvdata $ virsh domxml-to-native qemu-argv qemuxml2argv-disk-virtio.xml >1.dom
error：An error occurred, but the cause is unknown

Best Regards,
Olivia
