I have installed virtual box 6.1 and downloaded Kali Linux the latest release 2020.1 , ethernet seems to be connected but internet is not working. (This was with ping and a web browser.) I'm using Bridging mode but I also checked NAT option, where the VM gets a different IP scheme. My LAN subnet is 172.16.10.xxx. My host gets 172.16.10.59 and my guest gets 172.16.10.92. Guest and host are using the same DNS servers, provided through DHCP. Host works. Guest doesn't.
