# find network
(vm) ifconfig | grep <id from first command>
(vm) > br-f5c43d88f2b6 Link encap:Ethernet HWaddr 02:42:E7:82:DF:BA
# add a delay rule to the network interface
(vm) tc qdisc add dev br-c0aca63f9c15 root netem delay 500ms
# remove delay rule from the network interface
(vm) tc qdisc del dev br-f5c43d88f2b6 root netem
