Hi all,
we have several OpenVZ instances (CentOS 4.5) running on several
physical servers (CentOS 5.0) as a QA-/testing environment for Java
applications running in JBoss application server. Since we do have to
test clustering, multicast has to work for all virtual servers, no
matter which physical host they run on.
Right now, we use veth interfaces with local IPs (192.168.*.*) and
tested multicast with ssmping (http://www.venaas.no/multicast/ssmping/)
without success.
Any idea how to get this running?
Regards,
Peter

Peter,
Is the same setup working without openvz?
Have you used multicast before? Multicast is a bit complex to set up,
requires support from routers/switches etc., so this might well be not openvz-related.
But we setting up this test case right now to check ourselfes.
Can you please also provide a bit more information about your configuration
like whether you use bridge for veth-eth0 traffic bridging or routed networking,
any configuration options (including sysctl) you used/changed etc.?
Thanks,
Kirill

Please, print ssmping command, output for ifconfig, route -n, etc.

One thing that is worth noting: I found a bug in the ... veth code, I
think, where it wouldn't pass a multicast packet through. The code
checked with the 'is_broadcast' flag, for a matching mac, and assumed
that anything else was not for this host.
Perhaps this is a similar issue? I can try to dig out the fault report
if it helps, but at the time it was simply changing is_broadcast to
include an is_multicast test on the Ethernet MAC.
Regards,
Daniel
I hope that actually helps. :)

plz make sure you really use and look at the sources of 028stab039 kernel.
this check in veth_xmit() was fixed in 028stab034 with this commit:
http://git.openvz.org/?p=linux-2.6.18-openvz;a=commitdiff;h=993241dcdfc8ae22d339e08ed78db6e9760b1d89

and it started to work?

We use several JBoss clusters with multicast in our datacenters.
Multicast itself works between the physical hosts:
ssmping joined (S,G) = (192.168.198.54,232.43.211.234)
pinging S from 192.168.198.53
unicast from 192.168.198.54, seq=1 dist=0 time=1.513 ms
multicast from 192.168.198.54, seq=1 dist=0 time=1.528 ms
unicast from 192.168.198.54, seq=2 dist=0 time=0.107 ms
multicast from 192.168.198.54, seq=2 dist=0 time=0.115 ms
unicast from 192.168.198.54, seq=3 dist=0 time=0.097 ms
multicast from 192.168.198.54, seq=3 dist=0 time=0.104 ms

unicast from 192.168.198.54, seq=6 dist=0 time=0.119 ms
multicast from 192.168.198.54, seq=6 dist=0 time=0.130 ms
--- 192.168.198.54 statistics ---
6 packets transmitted, time 5276 ms
unicast:
6 packets received, 0% packet loss
rtt min/avg/max/std-dev = 0.097/0.341/1.513/0.524 ms
multicast:
6 packets received, 0% packet loss since first mc packet (seq 1) recvd
rtt min/avg/max/std-dev = 0.104/0.352/1.528/0.526 ms
If I try the ssmpingd/ssmping between two virtual instances on two
different hosts (or from one virtual instance to a physical host an vice
versa):
pinging S from 192.168.198.142
unicast from 192.168.198.132, seq=1 dist=1 time=2627.063 ms

I never got to test it; that particular job (enable CUPS server browse
announcements in a VE) is still outstanding on my list because it was
low priority. (sorry)
