No networking for Centos under VirtualBox
Clash Royale CLAN TAG#URR8PPP
Running an Ubuntu desktop server. I installed virtual box, then installed CentOS as a virtual machine. Centos is not starting the eth0 network adaptor. When I start it manually, I cannot connect outside the machine.
Anyone know what I've done wrong?

The issue with this appears to have been the NAT setting. It requires you to use 10.0.2.* addresses.
To change the default network go to VirtualBox Manager's preferences and click on the Network tab. Click on the edit icon and modify the Network CIDR to the network you need for your guests. If you need to enable/disable either DHCP and/or IPv6 as well, go ahead and toggle the check boxes to your needs.
Also, when I thought about, NAT doesn't provide me with external access to that IP address. I changed it to bridged and everything now appears to be working.
Thanks for the help.
