For a "normal" new arch, it should be pretty simple.
1) Create the new directory in src/resmom/
2) Add the new directory to DIST_SUBDIRS in src/resmom/Makefile.am
3) Add the new Makefile to configure.ac's AC_OUTPUT
4) Modify buildutils/pbs_mach_type to recognize the new arch
5) Write new pbs_resources manpage in doc/man7/
6) Add new manpage to doc/Makefile.am
The tricky thing here is the buildsystem builds pbs_mom for the arch
that you are building on, which is wrong if you are building for some
But it is unclear to me if you actually want a new arch. You said that
you want pbs_mom to launch preconfigured VMs for new jobs, which implies
that pbs_mom is running on the genuine host OS. That sounds like you
want to modify the existing pbs_mom to spawn jobs under VMs.
On the other hand, if you wanted to virtualize pbs_mom to run in a guest
OS, then just use the existing pbs_mom for the guest OS without
