Minikube unable to start vm on Centos 7 on AMD processor

[anewton81]

Hello,

I have installed minikube v0.34.1 on linux (amd64), command line "minikube start"

I am running the latest fully patched Centos 7.6, but kernel version 3.10.0-862.el7.x86_64 (the initial kernel version from Centos 7.5 install ISO, along with kernel-devel and kernel-headers of the same version because the kernels kernel-3.10.0-957+ constantly hang on my machine due to nouveau video driver issues with my nVidia card). VirtualBox configured just fine with this kernel version.

When I do "minikube start", here is the result:

minikube start

This error message is incorrect, the virtual technology IS turned on in the BIOS. The lscpu command verifies this:

The only thing I can see is that lscpu is reporting "AMD-V" and the error message says there is no "AMD-v". Is there a lettercase issue in the test in minikube?

Help appreciated, thank you. Please let me know if I need to provide additional information.
