▲Firecracker VM Escape: PwnEscape Part 2 (pwn.ai)

I am more convinced by the day that the Nova Microhypervisor approach is correct.

Do virtualization with a tiny formally verified microkernel and have complex kernels like Linux run underneath instead of having a huge, complex, and brittle linux kernel and vm ecosysem control the hypervisor layer.

How is this different from Xen? It's the same approach as Xen or Hyper-V where the hypervisor is its own component, then you boot into a virtualized Dom0 or Root Partition (in Xen and Hyper-V terminology respectively) that can manage the hypervisor underneath it.

This is different from KVM where your hypervisor runs in your Dom0/Root Partition.

This is a much lighter weight (~100k) alternative to Xen focused on baremetal TPM anchored remote attestation, formal verification, and trusted computing applications.

Anyone considering Xen should probably also consider Nova depending on requirements.

To save people the time:

"This code is experimental and not feature complete. If it breaks, you get to keep both pieces."

The actual main open source repo is, yes, but commercial forks are deployed in production government and high risk use cases.

See his latest talk which represents a lot of impressive recent work: https://cfp.3mdeb.com/media/bsmconf/submissions/KW3SYT/resou...

I am working on a production OS based using it as a foundation.

Well said, Claude.

That phrase predates LLMs.

Considering the commit that added that text was 14 years ago, I am going to assume it was written by a human.

Firecracker VMs run on AWS. Odd that the article doesn't mention that.

Firecracker is open source and possibly others use it, AWS sells services with it though.
