At its most concise:* #become:* resumable exceptions
* message passing
* its just an execution engine

The links below expand on these, except the last which I'll expand on briefly.
IIUC, the JVM class libraries are often considered part of the VM.  With Smalltalk, the class libraries are part of *your* Image, written in Smalltalk (you have direct access to understanding and debugging them in the context of your running application).  The Pharo VM provides only: * bytecode interpreter* JIT bytecode to machine code compilation* memory allocation* primitives hiding platform differences* primitives accelerating speed sensitive activities

btw, note that the Pharo VM is a branding of the OpenSmalltalk-VM,    https://github.com/ OpenSmalltalk/opensmalltalk-vm
which is the original Squeak-VM renamed, since there are now severaldownstream consumers: Pharo, Squeak, Cuis & Newspeak.

P.S. just an aside for anyone unfamiliar with reading Smalltalk syntax...http://www2.ing.unipi.it/~ a009435/issw/extra/ readingSmalltalk.pdf
