VIRUS SCANNING FOR BLOCK-LEVEL DISTRIBUTED APPLICATION MANAGEMENT

Described herein is technology for, among other things virus scanning for block-level distributed application management. The technology involves storing blocks of a root image on a first storage unit and storing blocks of leaf images on respective second storage units. The leaf images include additional data blocks not previously contained in the root image and changes made by respective compute nodes to the blocks of the root image. The technology includes receiving a notification from one of the compute nodes that the root image has been scanned for viruses and providing the notification to other compute nodes.
