I have successfully installed Arch Linux on VirtualBox but the internet is not working in it. There was no issue with the internet connection during the installation but when I boot from the virtual hard drive (using syslinux bootloader) I'm unable to connect to the internet.
When I boot from the installation CD and mount the root partition and then use installed system from
# arch-chroot internet works well without doing anything at all and
# ip link shows two interfaces
When I try to use
# systemctl enable email@example.com command, it gives an error 'Operation failed: No such file or directory however
# ip link says there are two interfaces
I want to know why there are two different names for the same ethernet port? and more important how do I solve this problem?
