Abstract:
Virtual disks are the main form of storage in today's virtual
machine environments. They offer many attractive features, including
whole system versioning, isolation, and mobility, that are absent
from current file systems. Unfortunately, the low-level interface
of virtual disks is very coarse-grained,
forcing all-or-nothing whole system rollback, and opaque, offering
no practical means of sharing. These problems impose serious limitations on
virtual disks' usability, security, and ease of management.
To overcome these limitations, we offer Ventana, a virtualization
aware file system. Ventana combines the file-based storage
and sharing benefits of a conventional distributed file system with
the versioning, mobility, and access control features that make
virtual disks so compelling.
