Hello oVirt users,
I'm running into network setup problems.
http://www.ovirt.org/Vdsm_Network
Shows this as a supported topology.
bridge1 --- v1 --- bond --- nic1
bridge2 --- v2 --/ \-- nic2
Problem is I have to configure at least this on each host in order to the connect to an
activate:
v1 --- bond --- nic1
\-- nic2
Which oVirt does not like because I already created the bond and attached a vlan interface
to it.
So I configured this ahead of time (without vdsm)
bridge1 --- v1 --- bond --- nic1
bridge2 --- v2 --/ \-- nic2
Those work fine. I can use each bridge statically or with DHCP.
Problem is that oVirt refuses to use the bridge interfaces (they don't show up in the
web gui), it only wants to use the bond interface.
If I was using libvirt/kvm-manager I would preconfigure this (without vdsm):
bridge1 --- v1 --- bond --- nic1
bridge2 --- v2 --/ \-- nic2
And I'm be able to run VMs on other VLAN. (Which is what I want to achieve with
oVirt).
Is there a way I can achieve what I need to do (connecting VMs to either VLAN) with one of
my preconfigured setups without resorting to another nic (or bonded pair?)

Hi,
the "solution" to your problem
is, that you don't need to setup
any "on top" networking at all, after basic
setup, so: no bonds, no vlans.
Just configure everything in ovirt, you
can easily construct some bonded setup
with v-lans on top, ovirt creates it all for you.

Yes, I've found that out doing some more playing around with it.
However, I can't connect to it initially without an existing minimal
setup, which requires me to have set up the bond and and at least one
vlan.
If I use an initial vlan tag that is not one that OVirt networks will
need to use, then I'm getting Ovirt to cooperate.

What do you mean by "not like"? If v1 has an IP address attached to it,
you should be able to add this host to an oVirt cluster.
Once the host is added, you can use the GUI to seup more stuff on your host.
So I configured this ahead of time (without vdsm)
bridge1 --- v1 --- bond --- nic1
bridge2 --- v2 --/ \-- nic2
Those work fine. I can use each bridge statically or with DHCP.

I would not recommend this, but you could define a libvirt network per
bridge to make it show in the web gui:
<network>
<name>vdsm-bridge1</name>
<forward mode='bridge'/>
<bridge name='bridge1' />
</network>
If I was using libvirt/kvm-manager I would preconfigure this (without vdsm):
bridge1 --- v1 --- bond --- nic1
bridge2 --- v2 --/ \-- nic2

By "not like" I mean I can try to configure oVirt networking but it
won't work with the way I had it set up.

bridge to make it show in the web gui:
<network>
<name>vdsm-bridge1</name>
<forward mode='bridge'/>
<bridge name='bridge1' />
</network>
Thanks. I don't think I'll need to use that since I've found that if I
use an initial vlan interface with an id I won't be using in the oVirt
networking setup then I don't run into problems. While I need to have
some initial network pre-configuration, I've found out who to do it in a
way that oVirt will accept and work with.
