when I try to start my freshly installed boot2docker 1.5 (got aware of the 1.6-bug) on windows8 there's the message, "no ip found for eth1". I tried to re-install VirtualBox, but still the same message.
Even if I empty the HostOnly-Card of which the MAC matches the message loading boot2docker - without or with reinstalling the problem persists.
The problem was a previous usecase for which I had VirtualBox installed before. All the config-data isn't deleted during uninstall. So I suppose it was that old xml-config containing some networking-details that were re-imposed on each new install-process.
After deleting everything being in folders containing "VirtualBox" everything got really re-installed and configured anew and boot2docker worked like a breeze.
