Example 9 with PIF

use of com.xensource.xenapi.PIF in project cosmic by MissionCriticalCloud.

the class CitrixResourceBase method enableVlanNetwork.

/**
 * enableVlanNetwork creates a Network object, Vlan object, and thereby a tagged PIF object in Xapi.
 * <p>
 * In XenServer, VLAN is added by - Create a network, which is unique cluster wide. - Find the PIF that you want to
 * create the VLAN on. - Create a VLAN using the network and the PIF. As a result of this operation, a tagged PIF
 * object is also created.
 * <p>
 * Here is a list of problems with clustered Xapi implementation that we are trying to circumvent. - There can be
 * multiple Networks with the same name-label so searching using name-label is not unique. - There are no other ways
 * to search for Networks other than listing all of them which is not efficient in our implementation because we can
 * have over 4000 VLAN networks. - In a clustered situation, it's possible for both hosts to detect that the Network
 * is missing and both creates it. This causes a lot of problems as one host may be using one Network and another may
 * be using a different network for their VMs. This causes problems in migration because the VMs are logically
 * attached to different networks in Xapi's database but in reality, they are attached to the same network.
 * <p>
 * To work around these problems, we do the following.
 * <p>
 * - When creating the VLAN network, we name it as VLAN-UUID of the Network it is created on-VLAN Tag. Because VLAN
 * tags is unique with one particular network, this is a unique name-label to quickly retrieve the the VLAN network
 * with when we need it again. - When we create the VLAN network, we add a timestamp and a random number as a tag into
 * the network. Then instead of creating VLAN on that network, we actually retrieve the Network again and this time
 * uses the VLAN network with lowest timestamp or lowest random number as the VLAN network. This allows VLAN creation
 * to happen on multiple hosts concurrently but even if two VLAN networks were created with the same name, only one of
 * them is used.
 * <p>
 * One cavaet about this approach is that it relies on the timestamp to be relatively accurate among different hosts.
 *
 * @param conn    Xapi Connection
 * @param tag     VLAN tag
 * @param network network on this host to create the VLAN on.
 * @return VLAN Network created.
 * @throws XenAPIException
 * @throws XmlRpcException
