Abstract

How we implemented PVH boot capability to the NetBSD kernel, allowing it to start straight from QEMU's -kernel parameter or Firecracker's VMM. In the process, we reduced boot time from 300 to 20ms, using methods borrowed from FreeBSD, and some in-house optimisations to get rid of unnecessary delays.
