Example 12 with Network

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

the class CitrixResourceBase method enableVlanNetwork.

/**
     * enableVlanNetwork creates a Network object, Vlan object, and thereby a
     * tagged PIF object in Xapi.
     *
     * 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.
     *
     * 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.
     *
     * To work around these problems, we do the following.
     *
     * - 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.
     *
     * One cavaet about this approach is that it relies on the timestamp to be
     * relatively accurate among different hosts.
     *
     * @param conn
