Hi, i have a question regarding multicast (i am new to multicast): I use the following commands to test multicast: iperf -s -B 224.0.66.66 -u (server) iperf -c 224.0.66.66 -u (client) It only works within the same VE. It does not work between different VEs. It does not work with a HN. It does not work between HN / VE (and other way around). It does not work between different HNs. Any ideas what to test? This is a debian box with custom kernel config (2.6.18-028stab035-1-openvz). Thanks, Ataraxis
Can you please describe your network configuration (ip a ls, ip ro ls in VE and HN). Do you use venet or veth device in VE?

You need to setup veth networking inside your VE. Also you will need to create a bridge on HN and add veth device and HN's eth0 device to it. http://wiki.openvz.org/Virtual_Ethernet_device
