Abstract
One or more techniques and/or systems are provided for non-disruptively addressing misalignment between a virtual data format and an underlying data format. Virtual data, such as a guest operating system of a virtual machine, may be stored within a virtual structure, such as a virtual machine disk, according to a virtual data format. The virtual structure may be stored within a storage device according to a storage data format. If misalignment is detected, then a new data container may be created within the storage device. A shim, sized according to a misalignment offset, may be inserted into the new data container in order to align the new data container with the storage device. Virtual data may be migrated from the virtual structure to the new data container to achieve alignment. During the migration, the virtual data may remain available from the virtual structure (e.g., a virtual machine may still execute).
