Abstract
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.
