Hi tudor,

     seems that your vm doesn't have the nic. so suggest you check the log
of hypervisor.

     which type of hypervisor are you using? qemu? pls make sure upgrade
the qemu version into 0.15 just from my experience.

     sudo yum -y install
http://mirror.centos.org/centos/6/os/x86_64/Packages/audiofile-0.2.6-11.1.el6.x86_64.rpm

     sudo yum -y install
http://mirror.centos.org/centos/6/os/x86_64/Packages/esound-libs-0.2.41-3.1.el6.x86_64.rpm

     sudo yum -y install
http://pkgs.repoforge.org/qemu/qemu-0.15.0-1.el6.rfx.x86_64.rpm




Best Regards.

Hi,


I've asked this question a few times on the IRC channel, and I have an open
question on ask.openstack.org but so far noone has managed to answer it
successfully.


I have installed OpenStack Grizzly on Ubuntu 12.04 LTS with Quantum and it
is up to date with the Ubuntu OpenStack respository.


I have a simple problem: the network interface is not being created when an
instance starts up.  Horizon seems to think that the interface is correct.
It lists:


IP Addresses
---------------
Officenet

However, in the logs of the instance I get:


ip: SIOCGIFFLAGS: No such device


...and the only interface that exists inside the instance is lo.


I don't appear to get any obvious errors in any of the quantum or nova
logs.


I believe that quantum is supposed to create a tap port on the OVS bridge
specified by externel_network_bridge (br-eth1), but this is not happening.
The network physical port connected via eth1 has a hardware DHCP server on
it, but it doesn't appear to assigning a network device on that bridge, so
the DHCP request is not being forwarded.


I have included my quantum config, l3_agent.ini, and the output of
ovs-vsctl as I guess these are the most appropriate.  (Removing
commented-out defaults)


Other than solving my particular problem, I'm also trying to understand the
process that occurs here.   What service (nova/quantum/something else?)
actually creates the port on the OVS bridge and links it to the instance's
virtual network device?


Thanks for the help,
Tudor.
