Debugging Tools and Techniques for Virtualized/Containerized Automotive Systems
summary
System uses AGL-KVM demo with an eight-core host and a 4-vCPU guest, instruments networking with perf and trace-cmd plus PCC and framegraph, and compares standard virtio-net to vhost-net. Measured iperf3 bitrates jump from 1.66 Gbit/s to 3.26 Gbit/s (~2x throughput), and trace sequences drop from ~411 μs to ~187 μs per sequence, attributed to moving emulation out of QEMU user space and fewer vCPU wakeups. Tools and scripts are ported to AGL and used successfully.
