[Announce] Introducing Tor VM – Tor in a virtual machine.


Tor VM is a small virtual machine that acts as a router and redirects your TCP traffic and DNS request through Tor while filtering out protocols that could jeopardize your anonymity. Tor VM is built using all open source software and is free.

There are many advantages to running Tor in a virtual machine. Any application on any operating system that uses TCP for communication is routed over Tor. By using a small virtual machine that acts as a router, protocols such as UDP and ICMP are filtered, preventing a compromise of your anonymity. Placing Tor in a virtual machine separates Tor from potentially insecure applications that could compromises Tor's integrity and your security.

The Tor VM ISO is designed to be run in a virtual machine, not on physical hardware. The ISO requires two virtual NICs to be used; one bridged interface, one OpenVPN Tun/Tap adapter. The Windows build of Tor VM is portable and includes QEMU to run the virtual machine, but requires Administrator privileges to install the Tap32 adapter. Traffic is routed through the Tap interface, into the VM, TCP and DNS are directed to Tor's Transport while other protocols are discarded, then Tor does it's magic with your traffic. More details can be found in the design documentation.

Lots of people are going to ask "What's the difference between JanusVM and Tor VM?", so I'll address this now. JanusVM was designed to be used by multiple users, runs HTTP traffic through Squid and Privoxy, and was build on top of Debian packages. Tor VM is built from entirely 100% open source software, is pre-configured to support only a single user, is much smaller in size, uses less memory than JanusVM, and works with QEMU. Is Tor VM going to replace JanusVM?? It's too soon to tell.

This software is in the late alpha stages of development; work is still in progress. For the time being, Tor VM is being hosted on the JanusVM server. Martin and I would appreciate it if a few of you would give Tor VM a go and provide us with your feedback. Feel free to review the We look forward to hearing from the community.

One last thing. Mad props to coderman! Martin did an amazing job hacking QEMU and the WinPCAP drivers in order to create an interface that is a raw bridge into the existing network card. This is just as good as VMware bridge service, if not better! It's Amazing work; make sure to take a close look at what is under the hood. Tor VM wouldn't have been possible if it wasn't for his insane amount of knowledge and skill. Let me be the first to say it; Thank You. :)
