Yes, Oracle VM does this.  Your mileage will vary according to which 
version of Xen you are using.

In this particular case you're cross-compiling.   Basically you want 
"gcc -m64 helloworld.c" to produce a 64-bit binary and once you've got 
that, the rest will be a breeze :-)  You'll probably want a 64 bit 
machine to test that on though so you might as well do the build on that.
