What are some common challenges faced by virtualization software engineers when optimizing system performance?

Virtualization Software Engineers often encounter challenges related to resource allocation, latency, and maintaining system stability while running multiple virtual machines. Balancing the demands of various workloads and ensuring efficient memory and CPU usage can be complex, especially in large-scale environments. Additionally, troubleshooting performance bottlenecks requires in-depth knowledge of both hardware and virtualization layers, as well as close collaboration with network and storage teams to ensure seamless integration and minimal downtime.
