It is in .../tools/libxc/xc_dom_compat.c and
.../tools/libxc/xc_hvm_build.c for PV and HVM respectively.

Ehm, you can only do xm create in dom0, so I'm not sure what you mean by
xm is written in python, but it calls out to C-functions, which in turn
makes hypercalls to the hypervisor to perform for example memory
allocation, setting up VCPU(s), creation of the actual domain (empty, to
be filled in), starting the domain, etc, etc.
The code for "xm create" is in .../tools/python/xen/xm/create.py.
