Worked on the kata-containers/kata-containers repository to deliver virtio-mem memory hotplug support for s390x virtual machines, enabling dynamic memory management across runtime-rs and QEMU. Developed QMP-based operations for setting up, resizing, and cleaning up virtio-mem devices, and integrated these into the build and template systems using Rust and Bash. Wired virtio-mem initialization into VM startup with robust error handling after QMP connection, and enhanced memory hotplug and unplug flows to prefer virtio-mem resizing while maintaining backward compatibility with pc-dimm. Added comprehensive test enablement and CI validation to ensure reliable memory hotplug functionality on s390x platforms.

May 1, 2026May 2026 performance summary for kata-containers/kata-containers: Delivered virtio-mem memory hotplug support on s390x (runtime-rs and QEMU) enabling dynamic memory management for s390x VMs. Implemented QMP-based operations (setup_virtio_mem, resize_virtio_mem, cleanup_virtio_mem_setup) and integrated virtio-mem configuration into the build/template system. Wired virtio-mem setup into VM startup with robust error handling. Enhanced memory hotplug/unplug flows to prefer virtio-mem resizing, with safe memory decrease and pc-dimm fallback preserved for backward compatibility. Added test enablement and CI validation to ensure reliable operation of memory hotplug on s390x.
