Hi guys,

Thanks, this clears it more why we have VM and display options and how it's used on the nics.

What hapens with me on a 3.2 installation when I want to attach a network without IP (VM option or not) to a Nic I get the noticed error like I told before:

Error while executing action Setup Networks: Illegal or Incomplete IP Address


Here is the error from the log:

Why does this happen on None Bootproto or DHCP ?

You should define the 'logical networks' which describe the networks of
your setup.
See the response to Nicolas on this thread of the steps to achieve it.
If wish to create a network dedicated to storage which shouldn't allow
VMs to use it, it should be defined as non-vm network.
Once the network is assigned to a cluster, you can add new network
interface to your VMs which defines to which bridges (vm networks) they
are connected: hence, segregating the VMs is done by the vlan-id of the
bridge the VMs are connected to.

The default gateway can be provided for the management network only. You
can define its IP address either as static by providing its known IP
address or letting it determine the address from the DHCP server.
You cannot select 'None' as boot-protocol for the management network
since then the engine will not be able to communicate with the host.

However you can select 'none' boot-protocol to any other networks if wishes.
