[Xen-users] Missing packets on Dom0 when sniffing bridge with wireshark/tethreal

[Paul Nader <paul.nader@xxxxxxxxx>]

Hi,

 

I have a Centos5 machine running xen 3.0.3-41 with two NICs each on its own subnet: 192.168.1.x and 192.168.0.x. All DomUs can talk to each other OK through two xen bridges. There are 3 DomUs: Dom0, Dom1 and Dom2

 

The scenario:

 

I’m trying to capture packets on Dom2 on 192.168.0.x from external devices that are sending SIP stuff to Dom1, but fail to capture any packets. I can only capture them if I run tethereal on Dom1. I’m setting the interface to collect in promiscuous mode, enabled all protocols, etc.

 

I can however capture ICMP and ARP packets on Dom2 on 192.168.0.x when I ping Dom1.

 

Is there anything I need to do to make the bridge assigned to 192.168.0.x relay _all_ packets to _all_ DomUs?

 

Thanks for any help,

 

Paul.
