Since macOS 11, macOS has been shipping with a native framework to run virtual machines which is called 'virtualization framework'.

After a quick introduction to Apple's virtualization framework, this talk will show how vfkit uses this framework from go with a focus on the bindings between Objective-C and go. These bindings are needed as the virtualization framework only offers Objective-C and Swift APIs.

CodeReady Containers runs an OpenShift cluster on a laptop or workstation using virtualization.

Recent developments have made it possible to skip running the OpenShift runtime, and to use it for the sole purpose of running containers with podman when using macOS or Windows. This talk will focus on one specific part of CodeReady Containers, which is its userland TCP/IP stack based on gVisor. We will explore why this was needed, and how the container -> VM -> host connectivity is achieved.

CodeReady Containers runs an OpenShift cluster on a laptop or workstation using virtualization. It's written in go, and uses KVM, HyperV or HyperKit depending on the OS it's running on. External network access is done through gVisor's userland TCP/IP stack which the virtual machine uses over virtio-vsock.

This talk will start with a short presentation of what CodeReady Containers is, explain why it needs a userland TCP/IP stack, but its main focus will be around virtio vsock, how to use it from go, and the differences to expect on the different hypervisors.
