KVM uses a combination of security-enhanced Linux (SELinux) and secure virtualization (sVirt) for enhanced VM security and isolation. SELinux establishes security boundaries around VMs. SVirt extends SELinux’s capabilities, allowing Mandatory Access Control (MAC) security to be applied to guest VMs and preventing manual labeling errors. I needed to record a demo on a Mac, I don't own a Mac and was contemplating borrowing one from a friend. Then I realised, I finally had an excuse to give this a go! I've been itching to since I read - Accelerated KVM guests on WSL 2, an awesome write-up on how to run accelerated KVM guests on WSL2 from @unixterminal. Thunderbolt ports on a Mac computer or another Intel-based PC are generally fully compatible with existing KVM Switch devices and displays. Depending on your Thunderbolt version, you can either switch between Thunderbolt sources using a DisplayPort-based KVM switch or a KVM switch based on another video standard with the help of video adapters.
Thunderbolt offers a connection with state-of-the-art speed and versatility, while consolidating data transfer, video output, and charging into a single compact connector. Thunderbolt ports on a Mac computer or another Intel-based PC are generally fully compatible with existing KVM Switch devices and displays*. Depending on your Thunderbolt version, you can either switch between Thunderbolt sources using a DisplayPort-based KVM switch or a KVM switch based on another video standard with the help of video adapters.

Thunderbolt 3 (USB-C) KVM Switches
The new Thunderbolt 3 standard with USB-C technology is a truly universal connection. With the help of USB-C docking stations / USB-C video adapters, you can connect your Thunderbolt 3 based computers to just about any existing KVM Switch device!*For example, you can use a HDMI-based KVM as a Thunderbolt 3 KVM Switch with USB-C to HDMI adapters.
Thunderbolt 1 & 2 use the same connector as Mini-DisplayPort, and support standard DisplayPort standard up to version 1.2. To switch between Thunderbolt 1 & 2 sources, you can use a Thunderbolt compatible DisplayPort or Mini-DisplayPort KVM Switch*:

* When adapting Thunderbolt to a different video standard or using a DisplayPort-based KVM switch, Thunderbolt-specific functionality, such as power transfer and chaining, are disabled. Thunderbolt compatible adapters are also required for adapting Thunderbolt standard.
