I have a CentOS Linux virtual machine. When I run ifconfig -a on it to get the IP, it reports back with what appear to be two different IP addresses:

ens192: 192.168.20.130

virbr0: 192.168.122.1

What are the differences between these, and which one should I use if I want to connect to my virtual machine?

(side note: I cannot connect to either of the IP addresses from an external machine right now)
