Booting MicroVMs in Under a Second
Depot CI 팀은 Cloud Hypervisor 기반의 마이크로VM을 1초 이내에 부팅시키기 위한 다양한 최적화 기법을 소개했다. 기본 Ubuntu 이미지의 불필요한 커널 모듈 제거, systemd 서비스 비활성화, cloud-init 대체 및 initramfs를 활용한 경량화된 init 시스템 도입 등을 통해 부팅 시간을 7~9초에서 1초 수준으로 대폭 단축했다. 이 과정에서 부팅 병렬화와 커널 커맨드라인 최적화도 적용되었다. 이러한 기술은 CI/CD 환경에서 빠른 VM 시작이 필수적인 상황에 매우 유용하다.

How we got microVMs booting in under a second

Depot CI's VM scheduler is just-in-time: no pre-warming, no warm pool of standby VMs. We stacked optimizations to get microVM cold boots from 7 to 9 seconds down to under a second, and this post walks through each one.

Cool, KVM-based AMD SEV-SNP support was recently added to Cloud Hypervisor! Including support for Google's oak stage0 firmware and IGVM image format.

@qyliss Similar situation with #VirtualizationFramework. I really could use user space networking with it, so I wrote a quick #Slirp backend for its UNIX socket target. Maybe you can reuse that same mechanism + tool with #CloudHypervisor - just implement a UNIX socket network backend 😁
