+write tracker
decent file system, but that needs an efficient direct I/O implementation
in the VFS layer which is still being worked on.
=== Write tracker ===
Write tracker is a feature of ploop that aims during live migration. When write tracker is turned on, kernel memorizes a list of modified data blocks. This list then can be used to efficiently migrate a ploop device to a different physical server, with minimal container downtime. User-space support for this is implemented in '''ploop copy''' tool and is used by '''vzmigrate''' utility.
