Example 63 with Network

use of com.xensource.xenapi.Network in project cloudstack by apache.

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
 *
 * @see CitrixResourceBase#enableVlanNetwork
