NetworkManager creates a slew of DHCP requests with Mininet 2.0, 2.1, and 2.2 #228
We observe about 3 lakh packets per second for an average 5 interfaces switch, 100 switch topology on mininet 2.1.0. When the same scripts are run using mininet 2.0.0 these packets are not observed. Doing a ls on /var/lib/NetworkManager on an ubuntu system while 2.1.0 is running displays .lease files aplenty. These files are never observed on mininet 2.0.0. If this is a bug please provide us workarounds. More, the CPU where the mininet (alone) is running shoots up over 93% in less than a minute.
