While your processor has SVM, it does not have the NRIP feature which is also required by bhyve. See e.g. http://svnweb.freebsd.org/base?view=revision&revision=272926 . That is why the VMM module wouldn’t load successfully.

See the “SVM” line in your dmesg output above, versus this one from a Phenom II X4 (which is running 10-STABLE with bhyve VMs successfully):
  SVM: NP,NRIP,NAsids=64
