When defining and creating networks, we have been checking to make sure there is only a single "default" portgroup, but haven't verified that no two portgroups have the same name. We *do* check for multiple definitions when updating the portgroups in an existing network though. This patch adds a check to networkValidate(), which is called when a network is defined or created, to disallow duplicate names. It would actually make sense to do this in the network XML parser (since it's not really "something that might make sense but isn't supported by this driver", but is instead "something that should never be allowed"), but doing that carries the danger of causing errors when rereading the config of existing networks when libvirtd is restarted after an upgrade, and that would result in networks disappearing from libvirt's list. (I'm thinking I should change the error to "XML_ERROR" instead of "UNSUPPORTED", even though that's not the type of error that networkValidate is intended for) This resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1115858
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.
