Hyperlight Nanvix: POSIX support for Hyperlight Micro-VMs
The Cloud Native Computing Foundation’s (CNCF) Hyperlight project delivers faster, more secure, and smaller workload execution to the cloud-native ecosystem.
I’m excited to announce a new blog post about something I find cool: interactive #debugging for #Hyperlight guests.
If stepping through your code running inside a hardware-protected micro-VM is your thing, give this a try.

Find out how you can step through code in your guest micro-VM by attaching the GNU Debugger at runtime to debug Hyperlight guest micro-VMs.
A long time coming for #hyperlight and any micro-guest -- including #webassembly -- interactive debugging across the hardware boundary and into the microguest. https://opensource.microsoft.com/blog/2025/07/14/hyperlight-debugging-hardware-protected-guests/
Great stuff by @dblnz !!

Hyperlight Wasm: Fast, secure, and OS-free | Microsoft Open Source Blog
We're announcing the release of Hyperlight Wasm: a Hyperlight virtual machine “micro-guest” that can run wasm component workloads written in many programming languages. Learn more.
A post for the geek in your life, which might be you anyway. Ludvig Liljenberg has written a post about creating a C-based function "micro-VM guest" for #hyperlight: with #QuickJS!! https://opensource.microsoft.com/blog/2025/03/10/build-a-hyperlight-c-guest-to-securely-execute-javascript/
Understand how -- and how fast -- you can protect an arbitrary .js file. Then run a bunch of things to test how it works!

Microsoft's Hyperlight WebAssembly for VMs Is Open Source
Hyperlight is a Rust library built to allow developers to leverage kernel-based virtual machines or Hyper-V — a Microsoft-native hypervisor — to run untrusted code in a micro VM without loading a full operating system.
Following on the first post about
#hyperlight,

The royally cool
@arschles has written about
#hyperlight, a project involving driving as much performance with density and protection as possible for
#webassembly.
