dukeleto, effectively the current leader of the Parrot project, writing in 2011: "the most important reason for M0 is {that} it is best for a virtual machine to minimize crossing language boundaries" and M0 supplied "high-level constructs and conveniences, such as objects, lexical variables, classes and their associated syntax sugar". While the details are of course different I find dukeleto's description of MoarVM as "the spiritual successor to M0" apt.

if MoarVM will ever run any Perl 6 code

That's FUD.

Update 5 months later: Rakudo/MoarVM is already compiling the core setting -- which is 18K lines of non-trivial Perl 6 code -- and passing ~26k of ~28k spectests.

Update a year later: Rakudo on MoarVM now passes more spectests than on other backends. It's startup, compilation, and run time are generally much faster and use much less RAM. Etc. In short, MoarVM is now firmly established as devs' most popular backend for most uses.

(To be clear, Rakudo on JVM has a few advantages: it runs on the JVM, which is necessary or desirable for some folk; it can interop with Java code; it's sometimes much faster for long running code due to its excellent and mature JIT; it has battle hardened threads which means concurrent code is currently more reliable.)

to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
