Hi,
I have tried this but still doesn't work. Here is my interfaces config of DomU:
auto eth0:1iface eth0:1 inet static address 192.168.110.1 netmask
255.255.255.0 broadcast 192.168.120.255 gateway 192.168.110.1
auto eth0:2iface eth0:2 inet static address 192.168.100.224
netmask 255.255.255.0 broadcast 192.168.100.255 gateway
192.168.100.1
and here is ifconfig of controller, domU and dom0:

Subject: RE: [Openstack] [OpenStack] Xen Hypervisor
Thanks for the info. The one thing I am missing is the ifconfig info from
inside your VM instance (I would personally use XenCenter to access the console
and see what is going on). I am assuming that it is not getting the correct IP
address from the DHCP server in nova-network. And I am assuming there is no
other DHCP server on that network. OK, so it looks like you have
this:--flat_network_bridge=xenbr0--flat_interface=eth0--network_manager=nova.network.manager.FlatDHCPManager--public_interface=eth0
Good news is that the DB looks to correctly have the flat_interface. I can’t
see how your DomU can be listening on 192.168.100.228, given your current
config0, looks like nova network has attached and reconfigured eth0 for you.
Are you launching instances using horizon or the nova CLI? One idea that might
make this work (others please correct me if I am wrong):· Add two extra
VIFs (virtual network interface) on your DomU VM· Attach those VIFs to
xenbr0, just like the other VIF that is eth0 on your DomU Now try the following
configuration:· Configure eth0 to have the IP address you want
(presumably it is a static address, as you can’t have a DHCP on that network
and use flatDHCP?): 192.168.100.238· Do not configure eth1 to have any
address· Configure eth2 to have another IP address that is public
facing: 10.42.0.42 / 255.255.255.0, something in the floating ip network maybe·
Change the flags:
--flat_network_bridge=xenbr0--flat_interface=eth1--network_manager=nova.network.manager.FlatDHCPManager--public_interface=eth2
That might leave things a little less broken than trying with a single
interface in DomU? However, I am no expert on how nova-network works, hopefully
others can confirm the best way forward. Cheers,John From:

Subject: RE: [Openstack] [OpenStack] Xen Hypervisor
Just double checking, but about the other machine you have put on the same
network as your VMs, is the interface configured in the same subnet as the VMs?
Also, Just to be clear, not sure anyone has ever tried the sort of setup you
are wanting (Single interface, with no VLANs). I have seen many setups using a
single interface and VLANs, and many setups using different physical
interfaces, and some combinations of the two, but I haven’t seen anyone try
collapsing everything onto a single physical interface. It might not work due
to the way nova network in flatDHCP works (i.e. adds a DHCP server onto your
network). Just checking, but you are using FlatDHCP networking, I presume? If
you haven’t assigned a floating ip and you are using some kind of flat
networking, the public network configuration should be largely unimportant. I
think you want these settings:flat_networking_bridge=xenbr0flat_interface=eth0
What is the state of your VM, does it seem to have the correct IP address from
the nova network DHCP? I think you are close with your flags now, but I can’t
be specific with the help without more information:· a list of your
flags in nova.conf· networking info (ifconfig or otherwise) from both
Dom0 and DomU (with compute running) and the VM· networking config from
XenServer (networks, DomU VIFs and VM VIFs)· a copy (in text form) of
the network related tables in your DB (or all the values from your “nova-manage
network create” and related calls) More general advice is: To make sure all the
new network settings get applied, I would recommend:stop all nova servicesreset
your nova DBdelete the old DBCreate the DB, do DB migration again, etc.Add in
your network again, (please tell us what values you use for that)start all nova
services It might be worth adding a second VIF on the same network, calling
that eth1 in the Nova domU and then using that as the flat_interface. Normally
it is not recommended that you configure an IP address on the interface that
nova-network uses for the guest networking. Not sure what you are trying will
work. Thanks,John From:
