  The e7500 model has VT-x, but not EPT so the vmm.ko kernel module 
should fail when being loaded. Hmmm, not sure the script would handle this.

  So, unfortunately your h/w doesn't quite have what BHyVe requires :(

  That is currently true, but your CPU is Intel - FreeBSD's generic term 
for 64-bit Intel architecture is "amd64" so that's not the problem.
