Great! It works but it wasn't obvious for me. Is it good idea to add this information to yours wiki? > I hope these explanations are not arriving too late.... No, they didn't arrive too late. I have worse news. I have more questions!:) If you don't mind I'd like to ask you about such corner case. Let imagine vde_switch process crash, next I start vde_switch again. Is it possible to readd VM to port without restarting qemu? After some reading it looks I have to use vde_plug2tap to do it. Am I right? I'd like to also ask about network speed. I did test between two VMs (both are using virtio driver for network adaper) using iperf. I got ~890Mb/s (ping shows latency ~0.4-0.5ms), are such values acceptable for VDE? Thanks again! Marcin P.S. Wiki and program help displays: vlan/addport N PORT add port to the vlan N (tagged) vlan/delport N PORT add port to the vlan N (tagged) shouldn't it be like: vlan/addport N PORT add port to the vlan N (tagged) vlan/delport N PORT delete port from the vlan N (tagged) ? ------------------------------------------------------------------------------ Symantec Endpoint Protection 12 positioned as A LEADER in The Forrester Wave(TM): Endpoint Security, Q1 2013 and "remains a good choice" in the endpoint security space.
