We have two (physical) machines. Each of them is hosting
one Linux Virtual Machine (HVM) on top of Xen Hypervisor 3.4.1, The VMs
are able to communicate with each other (using Xen Bridge Networking) thru the
ethernet on the physical hosts. However, Corosync (part of OpenAIS HA suite) in
VM is not able to detect and communicate with the other VM. We are not seeing
any messages exchanged between the nodes. We found that corosync generated
multicast messages are reaching the (Xen virtual) bridge. However, the
bridge is not forwarding the UDP multicast messages to the ethernet. Does
anybody know how to make multicast traffic flow across Xen Bridge? Also do we
need any special route setting to achieve multicast routing between VM hosted
on different machines.
