[Qemu-devel] [PATCH V3 for-1.6 0/5] Leaky bucket throttling and features

2013-07-23 Thread Benoît Canet
The first patch fixes the throttling which was broken by a previous commit. The next patch replace the existing throttling algorithm by the well described leaky bucket algorithm. Third patch implement bursting by adding *_threshold parameters to qmp_block_set_io_throttle. The last one allow to d
