Al,
VMware includes 'vmnet-sniffer (at least on my Ubuntu VMware server 2.0
installation). With that you can capture packets on any vmnet interface
(bridge). You can then read the packets from the file with wireshark.
If you want a realtime monitoring solution, you need to make sure the vmnet
(to which both VMs are connected) is bridged to an interface that libpcap
can capture. On my system I have created some vlan-interfaces for my virtual
machines and I can capture packets between VMs on the vlan interface (both
VMs using the same vmnet connected to that vlan). Actually the VMware bridge
behaves more like a hub than a bridge ;-)
Maybe it's even possible to create a special loopback interface for this
purpose, but I have not tried that yet.
Hope this helps,
Cheers,
Sake

Hi Jaap,
Yes can it be done on a VMWare virtual switch.

Hi,
If you can create a tap on such a vm switch you can monitor on that.
It very much depends on the specific technology you're using. VMWare
maybe?
Thanx,
Jaap

Hi,
We have a VM server that uses vm switches for communication between
the
VM's. Can WireShark or tshark monitor communication on a VM switch
between the different servers that reside on the same physical host?
So
application server on VM1 on host A talks to Database on VM2 on host A
through a VM switch. We'd like to have WireShark monitor this
communication.
Thanks for the help.
