Could you build this?
No Writing a custom hypervisor faster than AWS Firecracker requires bare-metal Linux KVM programming, kernel virtualization mastery, and deep hardware architecture expertise.
What it would actually take: Building a type-2 hypervisor involves writing low-level Rust/C code directly against the Linux KVM API (`/dev/kvm`), creating virtual CPU registers, MMU page table handling, and minimal virtio devices (block, net). The team must optimize kernel boot paths, page fault handlers, and minimal device emulation to shave microsecond latencies off microVM initialization. This demands top-tier kernel engineering and low-level virtualization systems knowledge.
Discussion
5 comments analyzed.
Competitors mentioned: Firecracker, rust-vmm
Concerns raised: Memory shrinking not supported yet, only growth, 2x performance claim in headline not substantiated in documentation, No published benchmarks despite headline claims, Only suitable for terminate-and-rerun workloads, not multi-tenant scenarios
Feature requests: virtio-balloon support for dynamic memory management
