Hi, If you are using neutron then you can create pass the MAC address as part of the create port call. Please see https://wiki.openstack.org/wiki/Neutron/APIv2-specification#Port Thanks Gary From: varun bhatnagar <varun292006 at gmail.com<mailto:varun292006 at gmail.com>> Date: Tuesday, January 21, 2014 8:35 AM To: "openstack at lists.openstack.org<mailto:openstack at lists.openstack.org>" <openstack at lists.openstack.org<mailto:openstack at lists.openstack.org>> Subject: [Openstack] How to get the MAC Address in Openstack Hi, How can I get the MAC Address of the network interface which I have created on Openstack? Also, is there any way where in I can define the MAC Address while creating any network? I tried digging in the code and I found out that the MAC Address assigned by Openstack starts with "fa:16:3e:". I want to assign fa:16:3e:00:00:01 first network interface, fa:16:3e:00:00:02 to second and fa:16:3e:00:00:03 to third network interface of my VM. Is this possible?
