Hi all,

I couldn't see the following answered clearly in the literature, so I'll 
ask it here. 

When a freeBSD host is running a [anything] guest, a tap interface needs to be
created. Let's say I've done all this:

# ifconfig tap0 create
# sysctl net.link.tap.up_on_open=1
net.link.tap.up_on_open: 0 -> 1
# ifconfig bridge0 create
# ifconfig bridge0 addm igb0 addm tap0
# ifconfig bridge0 up

I want to add another tap, I don't want to restart the host. If I do

# ifconfig bridge0 addm tap1

then configure another vm to use tap1, can I expect it to work? Or, If I want 2
vns with 2 taps, do I need to do this:

# ifconfig bridge0 create
# ifconfig bridge0 addm igb0 addm tap0 addm tap1
# ifconfig bridge0 up

The reason I ask, is because I'm expecting a freebsd vm to work on tap1, and it's 
not.

thanks,
