About Firecracker
Firecracker adds PCI device hotplugging and virtio reset — microVM lifecycle management takes a meaningful step.
Firecracker is Amazon's open-source microVM hypervisor, used as the isolation layer for Lambda and Fargate. Recent releases have been focused on expanding the microVM lifecycle model: v1.16.0 added developer preview PCI virtio device hotplug (block, pmem, net), v1.17.0 adds virtio device reset support and richer metrics emission (instance ID and operator-defined properties). The release cadence has accelerated — multiple patch releases within the same minor version cycle.
