This isn't supported by ovirt. In order to ovirt to handle the nic properly it should be created by it. I'm not familiar with Nova-ovirt integration - noticed there is an unimplemented blueprint [1] and a PoC [2]. Which Nova-ovirt driver are you using ? [1] https://blueprints.launchpad.net/nova/+spec/rhev-m-ovirt-clusters-as-compute-resources [2] https://github.com/oourfali/openstack-ovirt-driver > 2) Delete the port created by OpenStack, in my driver code and recreate same > via oVirt by allow it to be created through oVirt? > Ignoring the driver for a second: Creating the vnic from within oVirt will create it on neutron. So if the issue is a taken mac address on neutron, removing the port from neutron and recreating it by ovirt should work. > > Please suggest your inputs. > > > Thanks much. > > Regards, > Udaya Kiran > > > On Tuesday, 17 June 2014 4:55 PM, Moti Asayag <[email protected]> wrote: > > > > > > ----- Original Message ----- > > From: "Udaya Kiran P" <[email protected]> > > To: "Moti Asayag" <[email protected]> > > Cc: "users" <[email protected]> > > Sent: Tuesday, June 17, 2014 12:37:23 PM > > Subject: Re: [ovirt-users] Nova- oVirt Driver : Adding NIC to VM > > > > Hi Moti, > > > > ThankYou for your inputs. > > > > I want a VM to be launched in oVirt, through Nova. i.e., When I say,launch > > new instance in OpenStack, internally VM should get created in oVirt Host, > > with the same mac address as assigned by OpenStack, get added to the same > > Network as selected in OpenStack. > > > > I am able to spawn a VM and run through the complete the full lifecycle > > (spawn, pause, reboot, terminate etc). > > > > Now, I am looking at how can I add NIC with the same mac address.
