Timekeeping and Time-Sensitive Applications in VMware Virtual Machines: Best Practices
When Virtualizing highly time-sensitive applications, additional care should be taken to ensure consistent performance and accurate timekeeping. In this talk we will review the fundamentals of timekeeping and scheduling for virtual machines as well as their interactions. We present best practices for configuring VMware ESX and Windows and Linux guest operating systems for accurate timekeeping and reduced virtualization-induced latencies for time-critical workloads. Diagnostic tools and techniques for identifying resource contention issues and tools for measuring and diagnosing timekeeping issues are also covered.
