The regression is introduced by Commit da1eba6b, the new
codes with this commit doesn't reset "ret" to "-1" when
it fails on parsing the device XML (live device attachment)
This patch changes the codes to reset the "ret" and "-1",
and also changes the codes so that it don't modify "ret"
for condition checking.
How to reproduce:
% cat test.xml
<disk type='oops' device='disk'>
<driver name='qemu' type='raw'/>
<source file='/var/lib/libvirt/images/test.img'/>
<target dev='vda' bus='virtio'/>
</disk>
% virsh attach-device $domain test.xml
Device attached successfully
The device attachment failed actually with error "unknown disk type 'oops'",
however, it reports success.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
