- File system journal is not bottleneck anymore
- Large-size image files I/O instead of lots of small-size files I/O on management operations
- Disk space quota can be implemented based on virtual device sizes; no need for per-directory quotas
- Number of inodes doesn’t have to be limited because this is not a shared resource anymore (each CT has its own file system)
- Live backup is easy and consistent
- Live migration is reliable and efficient
- Different containers may use file systems of different types and properties
In addition:
- Efficient container creation
- [Potential] support for QCOW2 and other image formats
- Support for different storage types
