Ewan, there seems to be an underlying problem that some people
are hitting more frequently than others - the virtual interface
just doesn't get created, and it seems to be non-deterministic
(occasionally passes). So we suspect yet another timing hole,
from what I can tell. Will have more for you today, although
there are a couple of other issues we're sidetracked on..

Getting trace output (set -x) from the scripts from everybody
would be good..

thanks,
Nivedita
