4 The dirty limit, short for dirty page rate upper limit, is a new capability
6 dirty ring to throttle down the guest during live migration.
35      CALCULATE(2), as the name implies. It involves preparing the dirty
37      The dirty page rate is calculated via the KVM dirty ring mechanism,
38      which tells QEMU how many dirty pages a virtual CPU has had since the
39      last KVM_EXIT_DIRTY_RING_FULL exception; The dirty page rate upper
46      computation must be done carefully in order to reduce the dirty page
49      subtract sleep time based on the ratio of the current dirty page rate
50      to the limit, which is used when the current dirty page rate is far
52      the current dirty page rate is close to the limit.

69 algorithm will restrict virtual CPUs as needed to keep their dirty page
