Yes. I like this idea to restart all services including nova, neutron, cinder, etc:)

It's not baked into devstack but I have a script called 'stack-smash.sh' which I run like

HOST=devstack.domain ./stack-smash.sh nova

to restart all the nova services in a running devstack.

#!/opt/local/bin/bash

if [ -z "$1" ] ; then
    set -- nova
fi

if [ -z $HOST ] ; then
    echo "HOST= $0 $@" >&2
    exit 1
fi

for service in "$@" ; do
    pattern=''

    case "$service" in
    nova)       pattern=^n-         ;;
    glance)     pattern=^g-         ;;
    cinder)     pattern=^c-         ;;
    keystone)   pattern=^key        ;;

                n-sch n-novnc n-cauth n-sproxy n-cpu c-api c-sch c-vol ; do

        [ -z "$pattern" ] && continue

        if [[ $win =~ $pattern ]] ; then
            echo -n "Killing window=$win for service=$service"
            ssh $HOST -qt screen -S stack -p $win -X stuff '' # this is a literal control-C
            sleep 1s
            ssh $HOST -qt screen -S stack -p $win -X stuff '!!\\n'
            sleep 1s
            echo " ... done."

        fi
    done
done
