Isn't it actually worse? There doesn't seem to be AMD support:

>Hosting Linux guests or FreeBSD guests with more than one vCPU requires VMX unrestricted mode support (UG)

Does AMD have UG or does this mean no AMD support for multi-processor guests?

With Meltdown and Spectre, doesn't this mean that VMs on linux AMD systems provide much better performance, and even better performance per dollar?

I dunno about the details but I've got a Debian VM with 6 vCPUs running on Bhyve, FreeBSD 11.3, on my Threadripper 1920X.

AMD doesn't need unrestricted guest support, it has always had it.
