Microsoft open-sources nvx, a lightweight hardware-isolated sandbox for AI agents

Microsoft's MSR and AzSRG teams have open-sourced nvx, a sandbox for agent workloads built on OpenVMM, according to Liam Arzola, who posted about the release on X. Arzola describes nvx as a lightweight, hardware-isolated microVM with unnecessary components removed, and says it is designed to support most agent workloads. The code is hosted at github.com/microsoft/nvx. Arzola's description is the only report so far, and no independent benchmarks or performance figures have been published.
