Hi,

The schedule tick interval of current credit scheduler (credit1) is 10ms. If one VM's timeslice is 15ms, 5ms(50 credits) will not be reduced from this VM's account, and another VM may be deducted 10ms (100 credits) when it only run 5ms. Is it right? And is there some good solution to handle this problem now? Thanks.

Regards,
Cong
