Hi,
I need help. I cant figure how to configure "logical networks" with my
servers.
My configuration is the following:
ovirt manager
        2 interfaces, eth0 and eth1 bonded
         ifcfg-bond0
            DEVICE=bond0
            IPADDR=192.168.44.105
            NETWORK=192.168.44.0
            NETMASK=255.255.255.0
            GATEWAY=192.168.44.254
            USERCTL=no
            BOOTPROTO=none
            ONBOOT=yes
ovirt hosts (2 servers)
        2 interfaces, eth0 and eth1 bonded for management
        ifcfg-bond0
            DEVICE=bond0
            IPADDR=192.168.43.10  (192.168.43.9 on the second server)
            NETWORK=192.168.43.0
            NETMASK=255.255.255.0 GATEWAY=192.168.43.254
            USERCTL=no
            BOOTPROTO=none
            ONBOOT=yes
2 interfaces, eth2 and eth3 bonded, used for VM networks.
This is my problem. These 2 interfaces are exposed to a network trunk
with a few vlan's. Do I need to create all the bridges for the vlan's at
the SO level?? Can I create them in the web interface? How can I find
some docs that point me in the right direction?
Ovirt/vdsm will create a ovirtmgmt network on top of you bonded 
interfaces which will leave you with no other physical nics to add your 
vlans from the webui. Don't know if its possible to add the vlans first 
and then on top of that ovirtmgmt but if yes, you'll loose the abilitiy 
to use the webui to manage vlans.
My setup consists of a nic dedicated to ovirtmgmt, 2 nics bonded into a 
storage network and 1-2 nics used for vlans. Don't know how 3.3 will 
handle vlans on ovirtmgmt.
