# Nested Virtualization

Nested virtualization allows workloads running on Namespace compute instances to use hardware-assisted virtualization (for example through `/dev/kvm` on Linux).

This is commonly used for Android emulator workloads and other virtualization-based CI tasks.

## Linux

Nested virtualization support on Linux depends on architecture and machine family:

| Linux platform | Nested virtualization support |
| -------------- | ----------------------------- |
| `linux/amd64`  | Supported                     |
| `linux/arm64`  | Supported\*                   |

\*For `linux/arm64`, support is available on Linux instances backed by Apple Virtualization, on Apple Silicon M4 and above.

## macOS

Nested virtualization is not currently available on macOS instances.
This is limited by Apple's Virtualization Framework and its nested virtualization constraints.

## Windows

Nested virtualization is not currently available on Windows instances.

## Android emulators

Android emulator hardware acceleration on Namespace currently requires `linux/amd64`.
For setup guidance, see [Android Emulators](/docs/integrations/android-emulators).
