      knowing that PIF1 get the whole traffic (i checked that by tcpdump -i eth1)
      the problem reside in VIF1, PIF1 not mirroring the traffic ti VIF1,

          something weird, i have only these interfaces :
          eth0 eth1 lo vif1 vif2 xenbr0 xenbr1

          i think normally i should have something like : vif0.1, vif0.2 bridged with eth0
          and vif1.1, vif1.2 bridged with eth1
          ???

            tcpdump -i eth1
            sniff all traffic
            tcpdump -i xenbr1
            sniff all traffic
            tcpdump -i vif2
            tcpdump: vif2: No such device exists
            (SIOCGIFHWADDR: No such device)

                i still cannot get this done, after reading some documentation i realized that xenserver has promiscuous mode issue in 6.5 and people complaining about that in citrix official support website,
                i think it is time to shift to vmware ESXI, i hope i can manage myself with it

                  Sorry that none of us have run into this issue. Why do you need promiscuous mode?

                    because i have an application that record voip calls, it need to catch the whole traffic, i configured a mirroring port on my switch that send all traffic to this VM, but unfortunately i was unable to get promiscuous mode working

                        Here is a response from a rather versed XenServer guide on their forums, even pointing to the same article.

                            @it-admin 4 years later, I encountered the same issue that you did.

                            The solution for me was do do a PCI passthrough of the physical NIC directly to the VM. This bypasses all virtual switching inside Citrix Hypervisor. I posted the exact steps to implement PCI passthrough on Citrix Hypervisor 8.2 here:
