No, I believe Xen does it automatically for me when I do "xl create",
using one of the vif-* scripts. I don't know which one actually, is
there a way of asking Xen to print which script it is using?

I attached the log (with a xl list to see the mapping vm<->id). The vif
interfaces do not seem to display any useful information in "ip a"; I'm
not sure if that's normal or not. Also, I don't know why, but the
unikernel seems to have two interfaces attached to it....

aHA. The vif* interfaces are correctly connected to the bridge, but
"brctl showstp br0" shows that vif3.0 and vif3.1 are in "state
disabled". (while vif 1.0 and vif2.0 are in forwarding state)
