Upcoming Talk: Running Wasmtime in Hardware-Isolated Microenvironments

At WasmCon, co-located with KubeCon + CloudNativeCon Europe 2026 in Amsterdam on March 23, Danilo (Dan) Chiarlone from Microsoft will present on running the Wasmtime WebAssembly runtime inside Hyperlight’s hardware-isolated micro-VMs. This talk will explore how combining Wasmtime with Hyperlight provides dual-layer security — a WebAssembly software sandbox inside a hypervisor-enforced VM boundary — while maintaining fast cold starts.

Upcoming Talk: Even More Hoops — Debugging WebAssembly across the Hardware Memory Partition Boundary

At Wasm I/O 2026 in Barcelona on March 19, Doru Blânzeanu will present on the challenges and solutions for debugging WebAssembly code running inside Hyperlight’s hardware-isolated micro-VMs. Building on Hyperlight’s GDB/LLDB debugging support, this talk will explore how to step through Wasm execution across the hardware memory partition boundary that separates the guest VM from the host.

Upcoming Workshop: Hands-On with Hyperlight and Wasm

At Wasm I/O 2026 in Barcelona on March 19, Lucy Menon, Ralph Squillace, and Tomasz Andrzejak will lead a hands-on workshop on building and running WebAssembly workloads inside Hyperlight’s hardware-isolated micro-VMs. This workshop will cover the practical steps of using Hyperlight Wasm — from compiling Wasm components to running them in sub-millisecond VMs with dual-layer security.

Hyperlight Nanvix: POSIX support for Hyperlight Micro-VMs

This post announces the integration of the Nanvix microkernel with Hyperlight, providing over 150 POSIX system calls inside hardware-isolated micro-VMs. By combining Hyperlight’s VM isolation with Nanvix’s minimal Rust-based microkernel, applications written in Python, JavaScript, C, C++, and Rust can now run with full hardware isolation and double-digit-millisecond cold starts — addressing the “serverless trilemma” of fast cold starts, secure isolation, and runtime compatibility. Written by Danilo Chiarlone and Pedro Henrique Penna.
