Noticed that parsing bond interface XML containing the miimon element
fails
<interface type="bond" name="bond0">
...
<bond mode="active-backup">
<miimon freq="100" carrier="netif"/>
...
</bond>
</interface>
This configuration does not contain the optional updelay and downdelay
attributes, but parsing will fail due to returning the result of
virXPathULong (a -1 when the attribute doesn't exist) from
virInterfaceDefParseBond after examining the updelay attribute.
While fixing this bug, cleanup the function to use virXPathInt instead
of virXPathULong, and store the result directly instead of using a tmp
variable. Using virXPathInt actually fixes a potential silent
truncation bug noted by Eric Blake.
Also, there is no cleanup in the error label. Remove the label,
returning failure where failure occurs and success if the end of the
function is reached.
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.
