  6624	If exit reason is KVM_EXIT_DIRTY_QUOTA_EXHAUSTED, it indicates that the VCPU has
  6625	exhausted its dirty quota. The 'dirty_quota_exit' member of kvm_run structure
  6626	makes the following information available to the userspace:
  6627		'count' field: the current count of pages dirtied by the VCPU, can be
  6628	        skewed based on the size of the pages accessed by each vCPU.
  6629		'quota' field: the observed dirty quota just before the exit to userspace.
> 6630	The userspace can design a strategy to allocate the overall scope of dirtying
  6631	for the VM among the vcpus. Based on the strategy and the current state of dirty
  6632	quota throttling, the userspace can make a decision to either update (increase)
  6633	the quota or to put the VCPU to sleep for some time.
