摘要： One embodiment of the present invention provides a system that facilitates storing an image file of a virtual machine on a potentially unprotected flash storage exhibiting sub-optimal non-sequential write performance on a mobile phone. During operation, the system stores in the flash storage data in a log-structured format and in a protected storage meta-data associated with the data stored in the flash storage. The system also checks integrity of the data stored in the flash storage using the meta-data in the protected storage.

摘要： Machine memory fragmentation in a computer system having a host operating system and virtual machine running on a hypervisor hosted by the host operating system is reduced by having the hypervisor identify and release those machine memory pages that are more likely than others to reduce the fragmented state of the host machine memory.
摘要翻译：具有主机操作系统的计算机系统和由主机操作系统托管的管理程序上运行的虚拟机的计算机系统中的机器内存碎片通过使管理程序识别和释放那些比其他机器存储器页面更可能的机器存储器页面来减少分散状态主机内存。

摘要： A computing device employs a cooperative memory management technique to dynamically balance memory resources between host and guest systems running therein. According to this cooperative memory management technique, memory that is allocated to the guest system is dynamically adjusted up and down according to a fairness policy that takes into account various factors including the relative amount of readily freeable memory resources in the host and guest systems and the relative amount of memory allocated to hidden applications in the host and guest systems.
摘要翻译：计算设备采用协同存储器管理技术来动态平衡在其中运行的主机和客户系统之间的存储器资源。根据该协同存储器管理技术，分配给客系统的存储器根据公平策略进行上下动态调整，该公平策略考虑到各种因素，包括主机和客户系统中容易可用的存储器资源的相对量，以及分配给主机和客户系统中的隐藏应用程序的相对内存量。

摘要： One embodiment of the present invention provides a system for managing storage space in a mobile device. During operation, the system detects a decrease in available disk space in a host file system, wherein an image file for a guest system is stored in the host file system. In response to the detected decrease, the system increases a size of a balloon file in a storage of a guest system. The system then receives an indication of a TRIM or discard communication and intercepts the TRIM or discard communication. Next, the system determines that at least one block is free based on the intercepted TRIM or discard communication. Subsequently, the system frees a physical block corresponding to the at least one block in a storage of the host system and reduces a size of the image file for the guest system in accordance with the intercepted TRIM or discard communication.
摘要翻译：本发明的一个实施例提供一种用于管理移动设备中的存储空间的系统。在操作期间，系统检测主机文件系统中可用磁盘空间的减少，其中用于客系统的图像文件被存储在主机文件系统中。响应于检测到的减少，系统增加客系统的存储器中的气球文件的大小。然后，系统接收到TRIM或丢弃通信的指示，并拦截TRIM或丢弃通信。接下来，系统基于截取的TRIM或丢弃通信确定至少一个块是空闲的。随后，系统释放与主机系统的存储器中的至少一个块相对应的物理块，并根据截获的TRIM或丢弃通信减少客系统的映像文件的大小。
