aws vm: Error : there are only 1 CPUs available.

[r-suresh-kumar]

Steps to reproduce the issue:

Pre-condition:
I am using Amazon EC2 linux instance with virtualization set to hvm.
But when I use command "grep -E --color 'vmx|svm' /proc/cpuinfo" to check if virtualization is enabled or disabled, it does not give any response.......I guess, virtualization is disabled. Please correct me if i am wrong

1. $ minikube start --vm-driver=none

OR

2. $ minikube start --driver=docker

OR

3. $ minikube start --no-vtx-check=false

minikube is exiting due to an error. If the above message is not useful, open an issue:

@r-suresh-kumar while the error looks scray and I appologize we need to make the error look better, and provide better action,

it seems that you are running minikube on VM with only 1 CPU ? the minimum required number of CPU cores are 2. could you please verify and try with a VM with higher CPU ccounts?

[r-suresh-kumar]

Thank you for the response. Let me check and fix your recommendations.

minikube needs 2 CPU's. We'll need to clean up the error message to be more actionable, as well as add a FAQ item.
