# allocated directly (they are in a holding experiment), but assign deals
# with it by allocating multiple vnodes on a pnode.
#
# The underlying physnode has to be "up", as determined by the
# autostatus stuff; this will prevent us from allocating a dead
# virtual node to an experiment.  This is especially hacky. We need
# another mechanism for this. We only add virtnodes when assign says
# we need them. This reduces the problem size for assign.
