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.
Microsoft Open Source BlogA 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.
Microsoft Open Source BlogA 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.
