I installed CentOS 7 in VirtualBox in OS X Yosemite, but the NIC is not getting an IP address. So I thought it was a problem with the thunderbolt adapter.

I’m running CentOS7 in VirtualBox 3.4.12 on RHEL6.5 without issues. Emulated network adapter is Intel PRO/1000 MT.

Do you have the network set to “bridge” mode in virtualbox?
Thanks,

Hmmm. I have windows 8.1, linux mint vm’s on my CentOS 6.5 box and they all work with networking, but CentOS 7 vm doesn’t have any networking. Do I need to install the VM tools for the network to work. I don’t remember having to do that. In cents 7 vm’s, I don’t get the nat’d IP address that is usually there :(
Thanks,

No. Nat. I tried bridging, but didn’t get any IP there too.

Didn’t install anything extra, just chose the “Gnome Desktop”
installation and everything works as expected. Network is NAT.

What does ifconfig show? Is eth0 up, if not try to manually start it.

I just installed linux mint/mate on both systems where I’ve been having issues with CentOS 7 and they both have eth0 working fine.
I had to go into /etc/sysconfig/network-scripts/ifcfg-enp0s3 and change ONBOOT=yes and reboot. I’m sure there is a management tool or something with Network Manager to do it, but the manual edit worked for me.

me too.
I think there is mention in the release notes that IF you do not enable networking during the install, when the system boots you have to manually enable it. Or maybe I misremember, perhaps it was: after the system comes up you have to go to network properties and toggle the on/off switch. something like that. (senior moment happening here.)
Thanks, that worked.
On the other system I did ifup enp0s3 and that activated the network. So for some reason the installer has the interface as default off.

Ah, the CentOS 7 install notes mention that Network is turned off by default, at least during install. I’m not sure about first boot though.
Ah, here are the notes. wiki.CentOS.org/FAQ/CentOS7#ethernet
Obviously CentOS 7 with systemd is not intended for networks :-)
Probably security. It gives you a chance to boot the new box up and tighten things down before turning on the Ethernet port.
To make it come up on first boot, go to the Configure -> General tab , in the network configuration section and say “Automatically connect to the network when available.”
You also have the option to bring up the Ethernet connection just during installation, which can be useful with DHCP in a netinstall.
