I'm trying to run the Catalyst Tutorial on OS X. I installed
VirtualBox and the tutorial according to the instructions on the
shadowcat website. Everything seems to work, except there is no
network connection, only the local loopback, lo 127.0.0.1.
Then I installed a Debian VM (same version as the Catalyst Tutorial),
and that works fine, meaning the Bridged Adapter gives a network
connection with an IP from my DHCP server.
