Abstract
Management of contexts that execute on a computer system is described. More specifically, context scheduling in a virtual machine environment is described. Times at which a context transitions from a scheduled state to a descheduled state and times at which the context transitions from a descheduled state to a scheduled state are recorded for each context. Skew is detected using the recorded times. The amount of skew can be quantified, and a corrective action is triggered if the amount of skew fails to satisfy a threshold value.
