20130054895 | COOPERATIVE MEMORY RESOURCE MANAGEMENT FOR VIRTUALIZED COMPUTING DEVICES - 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. | 02-28-2013 |

20130145073 | MEMORY DEFRAGMENTATION IN A HOSTED HYPERVISOR - 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. | 06-06-2013 |
20130185480 | STORAGE BALLOONING - 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. | 07-18-2013 |
20130254459 | BLOCK STORAGE VIRTUALIZATION ON COMMODITY SECURE DIGITAL CARDS - 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. | 09-26-2013 |
