[Bug 499491] Re: Eucalyptus 1.6.2 fails to boot an instance: Failed to add tap interface to bridge 'br0'

[Kees Cook]

Ah-ha!  I suspect it's recent changes to the initramfs that continues to
reduce the modules-needed-for-boot, which left out "tun".  I was able to
solve this by just "sudo modprobe tun" before attempting to start an
interface.  Hint found at:
