[one-users] Multicast problem

[Luis Rodero-Merino]

Hello,

We are able to run VMs with OpenNebula, but we have found that
multicast does not work properly. We are using a Ubuntu Server 10.04
based VM, virtualization with kvm. Multicast with that VM works fine
when running it in a local hypervisor. Multicast also works fine on
the physical hosts. But when the VM is started through OpenNebula,
although it has network connectivity (it can ping, ssh... other
hosts), we find it cannot even join multicast groups ¿Could this be
related with the bridge, or with the configuration that OpenNebula
passes to libvirt? ¿Has anyone found this before?

Thanks in advance for your help, regards,
Luis
