Could you define "total control"? > How to stop this "DHCP request" messages? It is not Open vSwitch that chooses whether DHCP client will be running for particular network interface. For example on Ubuntu 15.04, If I do ps -Af | grep dhclient root 1011 773 0 Jun22 ? 00:00:00 /sbin/dhclient -d -q -sf /usr/lib/NetworkManager/nm-dhcp-helper -pf /run/sendsigs.omit.d/network-manager.dhclient-wlan0.pid -lf /var/lib/NetworkManager/dhclient-cfb34368-76b5-4d00-93e0-6499bd8cf2cc-wlan0.lease -cf /var/lib/NetworkManager/dhclient-wlan0.conf wlan0 root 12214 773 0 11:30 ? 00:00:00 /sbin/dhclient -d -q -sf /usr/lib/NetworkManager/nm-dhcp-helper -pf /run/sendsigs.omit.d/network-manager.dhclient-eth0.pid -lf /var/lib/NetworkManager/dhclient-0e5f5c89-6b38-4564-941f-f7aa54b4deae-eth0.lease -cf /var/lib/NetworkManager/dhclient-eth0.conf eth0 And then search for parent process (773 in my case): root 773 1 0 Jun22 ? 00:00:22 /usr/sbin/NetworkManager --no-daemon It says that it is NetworkManager that started dhclient (and not any of Open vSwitch processes). So, if you don't want to run DHCP client on OVS interfaces, then make sure that you are using the right Network Manager configuration - http://support.qacafe.com/knowledge-base/how-do-i-prevent-network-manager-from-controlling-an-interface/ > > Thanks, > Hardik Soni > > ----- Original Message ----- >> From: "Gurucharan Shetty" <[email protected]> >> To: "Hardik Soni" <[email protected]> >> Cc: "[email protected] discuss" <[email protected]> >> Sent: Monday, 22 June, 2015 7:56:44 PM >> Subject: Re: [ovs-discuss] dhcp request originating from interfaces attached >> to OVS >> >> On Mon, Jun 22, 2015 at 10:54 AM, Hardik Soni <[email protected]> wrote: >> > Hi All, >> > >> > Is there any possibility that OVS allows DHCP request (broadcast) >> > originating from the interfaces(mostly virtual interfaces like tap/tunnel) >> > controlled by itself? >> Yes.
