QA:Testcase Virtualization Multicast

Description

This test is intended to test multicast on virtual machine

How to test

1. boot a virtual machine
2. log into this virtual machine, and join it three multicast groups

   ip maddr add 01:00:5e:c0:01:64 dev eth0

   ip maddr add 02:00:5e:c0:01:64 dev eth0

   ip maddr add 03:00:00:00:40:00 dev eth0

   01:00:5e:c0:01:64 is a IP Multicast macaddress

   02:00:5e:c0:01:64 is a General macaddress

   03:00:00:00:40:00 is a Lan Manage Multicast mac address

3. listen the multicast packets using tcpdump on this virtual machine

   tcpdump -ep ether multicast 2>/dev/null |tee /tmp/multicast.tmp 1>/dev/null

4. produce three random date packets and send to three multicast macaddress on host

   packet1 --> 01:00:5e:c0:01:64

   packet2 --> 02:00:5e:c0:01:64

   packet3 --> 03:00:00:00:40:00

5. sleep 20 seconds, and kill tcpdump processer in the virtual machine
6. copy the tcpdump result to host, and check if the tcpdump's result contains that three packets.

   grep content[i] /tmp/multicast.tmp

Expected Results

1. the tcpdump's result should contain that three packets.
