I'm using VLAN's under Xen, and have a question about the hardware NIC drivers. I can configure the VLAN stuff in one of two ways: 1. Phys + Bridge + VifX.0 | Veth0.X In this configuration, all frames (tagged and untagged) traverse a single bridge, and all VLAN's are available in all domains (obvious security problem, although I can work around it with ebtables). No hardware VLAN acceleration is available. Minimal virtual network interfaces and bridges are used. 2. Phys.X + Bridge.X + VifX.X | VethX In this configuration, the VLAN's are separated in Dom0 and each VLAN goes onto a separate bridge and (if required in Dom0) a separate Vif.X/VethX pair. A DomU requiring more than 1 VLAN will need multiple VifX.X interfaces, and managing all the separate VLAN's in Dom0 could be a real PITA. Hardware VLAN acceleration will be available if it works though, which could be nice for performance. Potentially needs lots of interfaces in Dom0, and will require configuration every time a new VLAN is required. Any suggestions or comments? In this scenario networking is really only going to be at WAN speeds (<2mbit/second), so maybe the performance side of things isn't critical.
