Nested virtualization on AMD ThreadRipper on Fedora 27

After much testing different kernel parameters and many emails between me and one of the kernel devs at Red Hat (I work there), I found a very simple solution to implementing nested virtualization on AMD ThreadRipper on Fedora 27.

Just run the 4.13 kernel for now. Everything works fine on 4.13. It turns out that 4.14 is broken for nested virt. That's all :/
