Hi, here's a new version of the series that adds support for performing I/O bursts for a user-defined period of time. Please follow the link to the first version of the series for a complete description.
There are two important changes in this version: a) The previous series was broken because the new parameters were missing from qmp-commands.hx. This is fixed now. [patch 10] b) This series has new tests and documentation [patches 14 and 16] I also added myself as maintainer of the throttling code [patch 17].
