Abstract: Page data of a virtual machine is represented for efficient save and restore operations. One form of representation applies to each page with an easily identifiable pattern. The page is described, saved, and restored in terms of metadata reflective of the pattern rather than a complete page of data reflecting the pattern. During a save or restore operation, however, the metadata of the page is represented, but not the page data. Another form of representation applies to each page sharing a canonical instance of a complex pattern that is instantiated in memory during execution, and explicitly saved and restored. Each page sharing the canonical page is saved and restored as a metadata reference, without the need to actually save redundant copies of the page data.

Abstract translation: 虚拟机的页面数据被表示为有效的保存和恢复操作。 一种形式的表示适用于每个页面，具有容易识别的模式。 根据反映模式的元数据来描述，保存和恢复页面，而不是反映模式的完整数据页面。 然而，在保存或恢复操作期间，表示页面的元数据，而不是页面数据。 另一种形式的表示适用于共享在执行期间在内存中实例化的复杂模式的规范实例的每个页面，并显式地保存和恢复。 共享规范页面的每个页面将作为元数据引用进行保存和恢复，而无需实际保存页面数据的冗余副本。
