Is there a way to determine what the hypervisor default NIC is? I'm
using kvm/libvirt/qemu. If this is the wrong forum please please reply
with that.

This is not really a question you want an answer to, because no matter what
the default NIC is, it is almost certainly the wrong NIC model to use for
the majority of operating systems.

Long story short, depending on what your quemu supports libvirt has a
preference function that tries to pick the most widely supported NIC model:
http://libvirt.org/git/?p=libvirt.git;a=blob;f=src/qemu/qemu_domain.c;h=0...
We don't query the OS in any way for the list of supported NIC models.
However, looks like virt-install has some logic on this matter too which
actually consults the guests OS (well, libosinfo):
