@Kees: Yes, that makes sense. Same issue seems to hit openvpn, bug
502081.
** Changed in: eucalyptus (Ubuntu)
Assignee: Thierry Carrez (ttx) => Dustin Kirkland (kirkland)
** Summary changed:
- Eucalyptus 1.6.2 fails to boot an instance: Failed to add tap interface to
bridge 'br0'
+ tun mod
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:

I've hit this same issue with all my libvirt-managed kvm VMs too:
$ virsh start sec-hardy-i386
error: Failed to start domain sec-hardy-i386
error: Failed to add tap interface to bridge 'br0': No such file or directory
** Also affects: libvirt (Ubuntu)
