Trace collection for a virtual machine

Trace collection for a virtual machine

One embodiment is a computer-implemented method of trace collection for a virtual machine that includes: executing a sequence of instructions from an initial state of the virtual machine; accessing an event log of data relating to nondeterministic events, which data includes an execution point; maki...

Zusammenfassung:One embodiment is a computer-implemented method of trace collection for a virtual machine that includes: executing a sequence of instructions from an initial state of the virtual machine; accessing an event log of data relating to nondeterministic events, which data includes an execution point; making at least a portion of the data available to the virtual machine when the sequence reaches the execution point; collecting trace information in response to expansion parameters; and storing the trace information in a trace file.
