802.1q vlan transfer from real to Guest

Hi All,

I have one topology as linked picture file. On that topology I traying transfer real device to Virtualbox Guest via VLAN from my Debian ethernet adaptor via eno2. On that topology all system can comminicate togather but real hardware to guest upload speed horribly low, for your example I can download with 1Gigabit speed from any VirtualGuest to real hardware but I can send from real to virtual guest with 3-5 Mbit speed. In this case I try passthrough my real ethernet to Virtualbox guest via intel iommu also my real cpu and main board can support this system, but this time I experiance another problem with virtualbox, Virtualbox want ich9 chipset for passthrough.

I am sure my all VLAN setup correct, because I never see any duplicate packet or wrong VLAN header on any packet, but I realy not understand why I can transfer my real hardware packet to Virtualbox Guest horribly low speed. So anyone can assit my about Linux core to Virtualbox VLAN transfer ? Why I do not understand but Virtualbox and Linux can not agreesss about VLAN packet comming from real to Guest.

Hos Operation System : Debian 9.3
Virtualbox : 5.2.6
Epension : ok
Real hardware Switch : DrayTek G2080
Guest Operation System : VyOs 1.1.8 ( Debian 6 )

Re: 802.1q vlan transfer from real to Guest

Hi All,

I fixed this problem, this problem coused from MTU.

Real Router WAN 1500 MTU -> Real Switch Port 2 to Port 1 MTU 1500 -> Real Server Ethernet Port ( bride or real one booth ) MTU 1500 -> Software Router LAN or any VLAN MTU 1500

So in this case real server can not transfer my packet to virtual router exacly, because of that I change my sistem as this,

Real Router WAN 1500 MTU -> Real Switch Port 2 to Port 1 MTU 9000 -> Real Server Ethernet Port ( bride or real one booth ) MTU 9000-> Software Router LAN or any VLAN MTU 9000 I know 9000 bayte is very big but maybe I will tray jumbo feame in future :).


in this moment all systerm work perfectly...
