Re: [Users] How do Networks and Vlan-tagging work in oVirt ?

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:

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. > I have decent setup switching network using Vlans, this is also the fact > for ovirt and the storage nodes where teh ports are seperated between > storage and management. > > Because I want to manage which client can acces which VM I need Vlan > tagging.

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. > I'm not able to set None or DHCP and can only add a network with IP, but > what IP and why ?
