nexus 1000V---vxlan and igmp

Recently, I  have met a problem about vxlan ,let me give you  detais:

I  have two ESXi  host  in my network, they are connected with an L3 switch,

ESXI1------------------------L3  switch-----------------------ESXI2

a VM called vm1 in Esxi1 is windows XP,  another VM called vm2  in Esxi2 is windows 2003 server,  I also have installed  cisco nexus 1000V VSM in Esxi1, and config vxlan to  connnect vm1 and vm2

my configeration about vxlan is in the 1000V-config.txt

when Vxlan is configed, vm1 ping vm2 successfully,  there is no problem. so I want to config vm1 as an multicast receiver,config vm2 as an multicast sender, I use VLC software to implement multicast receiver and sender. when I want vm1 to join a multicast group( for example 225.9.9.9), the IGMP report messages are not received in vm2 (I use wireshark to capture packet ) .  vm1 also have not received IGMP query message from vm2 . I  also  find that the multicast traffic sended by vm2 can be received in vm1.

so I use some troube shooting command to check it, the result is following:

1.   use "vempkt capture ingress ltl"

      ------this is ok,  I can capture the igmp report message(this is the original repoet message  not through Vxlan encapsulation) 

2.   use "vemlog debug sflisp all" and "vemlog debug sfvnsegment all"

      ------this failed. I can not see debug about encapsulate of IGMP report message

3.   use "vempkt capture egress ltl"

      ------this failed. I can not see the encapsulated message of IGMP report

I don't know whether my configeration about Vxlan miss something which support IGMP,   I Hope we can dicuss this problem and solve it.

Thanks for join the dicussion!
