I thought about replying to you when you first posted, but I didn't know how
to respond to bridging over wifi. The debian wiki has some pretty good info
on setting up a bridge for virtualbox. A few weeks ago, I updated the
example script that brings the interface up and down, and added a snippet of
my sudoers file that lets you run the particular commands without using a
password. On my system, all the tap interfaces are named vbox_{$vboxname},
and everything seems to be working just fine.
Here's the page: http://wiki.debian.org/VirtualBox
I didn't like adding the tap interfaces to /etc/vbox/interfaces, and I think
that the solution on the wiki page is much better than having to list static
interfaces there.
Btw, I've never heard of parprouted before. I just looked up the package and
it seems interesting. I might play with this later.
Using an ethernet bridge can be painful on a laptop sometimes, like when
there's no dhcp server on the network, and you have to give the br0 a static
address. That makes it much more difficult when the VM's are also expecting
to get their network info from dhcp. There are also problems when there is a
dhcp server, but there's no dns updates for the hostnames. This can get to
be annoying when you're using many VM's.
