| Hello! Debian stile would be:
in /etc/network/interfaces ==================== auto bond0 iface bond0 inet static
auto vlan1 iface vlan1 inet manual vlan-raw-device bond0
auto vlan2 iface vlan2 inet manual vlan-raw-device bond0
auto xenbr0 iface xenbr0 inet static address 192.168.0.13 netmask 255.255.255.0 gateway 192.168.0.1 bridge-ports vlan1
auto xenbr1 iface xenbr1 inet static bridge-ports vlan2 =====================
and setting in /etc/xen/xend-config.sxp
(network-script network-dummy)

In RH-style, it would be something like /etc/sysconfig/network-scripts/ifcfg-bond0.1 and I can't remember what the bridge stuff is like in the RH-style ones. Great! That sounds like what I was thinking. I have bond0 setup on the physical NIC which is connected to the trunked switch interface. So to set up the interfaces in dom0 I just need to create them using iface.vlan? Is this configured using a Xensource tool or by directly editing the /etc/sysconfig/network-scripts/? Thank you for such a fast reply!

Re: [Xen-users] VLAN help
1) Set up tagged VLAN interface and bring all VLANs in on single interface or on trunk (bond0).
2) Set up VLAN interfaces in dom0. In RH-type distributions this will be something like eth0.1, eth0.2, etc., or bond0.1, bond0.2, etc. In SuSE-type distros, they are vlan1, vlan2, etc.
3) Set up bridges for each of the VLANs. So, if I have vlan1 and vlan2, I set up xenbr1 and xenbr2 as bridges where xenbr1 has vlan1 as a bridge member and xenbr2 has vlan2 as a bridge member. Also, if you want dom0 to have an IP address assigned on any of the VLANs, assign it on the bridge for the VLAN and not the VLAN interface itself.
4) Configure my domUs with bridge=xenbr1 for VLAN1, bridge=xenbr2 for VLAN2, etc.
I've pretty well settled on this as a standard and it works fairly well - it provides a consistent setup on all of my XEN servers so that moving domUs between them works w/o having to reconfigure.
We are in the process of setting up a few Xensource servers whose initial function will be to run Exchange 2007. As part of this (and for future VM’s) I need to be able to provide access to various VLANS to the various DOM’s. In theory this sounds fairly straight forward: DOM0 gets a PIF for each VLAN. This PIF connects to a VLAN specific bridge and then, for each DOM that needs one, a VIF is created and connected to the bridge. If so, my question is how to specify the VLAN for a PIF. I can list it but I am not able to set it since it is read only. How do virtual networks fit into the above and how is a virtual network different from a virtual bridge? Any help or pointers to information are greatly appreciated.
