Changes

* '''Disk space'''. In a default setup, all containers reside on the same hard drive partition (since a container is just a subdirectory).OpenVZ introduces a per-container disk space limit to control disk usage. So, to increase the disk space availableto a container, one just needs to increase that limit -- dynamically, on the fly, without a need to resize a partitionor a filesystem.

* '''Disk I/O priority'''. Containers compete for I/O operations, and can affect each other if they use the same disk drive. OpenVZintroduces a per-container I/O priority, which can be used to decrease the "bad guy" I/O rate in orderto not trash the other containers.
