the class CitrixResourceBase method getNetworkByName.

/**
     * getNetworkByName() retrieves what the server thinks is the actual network
     * used by the XenServer host. This method should always be used to talk to
     * retrieve a network by the name. The reason is because of the problems in
     * using the name label as the way to find the Network.
     *
     * To see how we are working around these problems, take a look at
     * enableVlanNetwork(). The following description assumes you have looked at
     * the description on that method.
     *
     * In order to understand this, we have to see what type of networks are
     * within a XenServer that's under CloudStack control.
     *
     * - Native Networks: these are networks that are untagged on the XenServer
     * and are used to crate VLAN networks on. These are created by the user and
     * is assumed to be one per cluster. - VLAN Networks: these are dynamically
     * created by CloudStack and can have problems with duplicated names. -
     * LinkLocal Networks: these are dynamically created by CloudStack and can
     * also have problems with duplicated names but these don't have actual
     * PIFs.
     *
     * In order to speed to retrieval of a network, we do the following: - We
     * retrieve by the name. If only one network is retrieved, we assume we
     * retrieved the right network. - If more than one network is retrieved, we
     * check to see which one has the pif for the local host and use that. - If
     * a pif is not found, then we look at the tags and find the one with the
     * lowest timestamp. (See enableVlanNetwork())
     *
     * @param conn
     *            Xapi connection
     * @param name
     *            name of the network
     * @return XsNic an object that contains network, network record, pif, and
     *         pif record.
     * @throws XenAPIException
     * @throws XmlRpcException
