In virtualized environments, guest memory defragmentation is essential for exploiting huge-page benefits and improving application performance. However, existing approaches directly reuse host-side defragmentation and assume a limited guest physical address (GPA) space. As a result, they rely on...

Read-only compressed file systems have become increasingly popular in space-sensitive scenarios, such as IoT and Docker containers. To construct condensed images, they divide the data into blocks (e.g., 1 MB) and compress blocks separately. However, we observe that block-based compression cannot...
