Keeping this -just- on xen-devel - Which interface are you talking about being > 1500 bytes? Are you trunking a VLAN into a server via domU and then using the bridging code to split these vlans up across different vif's? Or are you bringing in a VLAN trunk into a domU somehow and running vlans inside the domU? (Snip discussion about IP, fragmentation and the like. Its useful to understand -why- there's a problem but not to understand what you're trying to do; and thusly what needs fixing.)
