I use Centos7.4 LEDE | LEDE Reboot 17.01.3 r3533-d0bf257c46
This system doesn't provide enough entropy to quickly generate high-quality random numbers.
Lede identifies CPU, Model, KVM (Redhat, KVM, CPU), What is the reason for this? Does kernel compilation not open support for virtualized processors?
