    • According to some embodiments, it may be determined that a first field in a first table is to be linked to a second field in a second table. A computer processor may then automatically create a new entry in a linked field table, the new entry including a linked field identifier, a source value, a source link referring to the second field in the second table, and a link counter containing a value indicating that one field refers to the second field in the second table. The first field in the first table may then be updated to refer to the new entry in the linked field table.
    • 根据一些实施例,可以确定第一表中的第一字段将被链接到第二表中的第二字段。 然后,计算机处理器可以在链接的字段表中自动创建新的条目,该新的条目包括链接的字段标识符,源值,引用第二个表中的第二个字段的源链接,以及包含指示 该一个字段是指第二个表中的第二个字段。 然后可以更新第一表中的第一个字段以引用链接字段表中的新条目。

    • A method for migrating a virtual machine (VM) in a computing environment is provided. The method comprises receiving a request to migrate a VM executing on a source host to a destination host; defining a recovery point to which the VM is restored during recovery from a fault; and iteratively copying a memory of the source host associated with the VM to the destination host. During the copying, the original state of each page in the memory is preserved. At some point, the VM suspends executing on the source host, copies state information associated with the VM to the destination host, and resumes executing on the destination host. If a fault is detected on the source host, the VM is restored to the recovery point using preserved information.
    • 提供了一种用于在计算环境中迁移虚拟机(VM)的方法。 该方法包括接收将在源主机上执行的VM迁移到目的地主机的请求; 在故障恢复期间定义恢复虚拟机的恢复点; 并将与VM相关联的源主机的存储器迭代地复制到目的地主机。 在复制期间,保存内存中每页的原始状态。 在某些时刻,VM暂停在源主机上执行,将与VM关联的状态信息复制到目标主机,并恢复在目标主机上执行。 如果在源主机上检测到故障,则VM将使用保留的信息恢复到恢复点。
