Hi All, This is the dm-ioband version 1.12.0 release. dm-ioband is an I/O bandwidth controller implemented as a device-mapper driver and can control bandwidth on per partition, per user, per process , per virtual machine (such as KVM or Xen) basis. The major change of this release is that a new bandwidth control policy "range-bw" is supported. This policy is developed by Dong-Jae Kang,

Hi all, These are new releases of dm-ioband and blkio-cgroup. The major changes of these releases are: - dm-ioband can be configured through the cgroup interface. The bandwidth can be assigned on a per cgroup per block device basis. - The event tracing is supported that helps in debugging and monitoring dm-ioband. - A document for blkio-cgroup is available at

Hi all, These are new releases of dm-ioband and blkio-cgroup. The major change of these releases is that a hierarchical configuration is supported, a parent cgroup's bandwidth is distributed to its children. The hierarchical configuration is available when using dm-ioband and blkio-cgroup together. Please refer to the documentation included in this series of patches on how to use it. The
