Version-Release number of selected component (if applicable): corosync 1.2.0-0ubuntu1 How reproducible: Hardcoded into system. Steps to Reproduce: 1. Two hosts linked by an ethernet 2. Libvirt in routed mode. 3. Virtual machines sat on a 10.x.x.x/30 subnet. 4. Unicast routing in place (I'm using bird and OSPF). 5. Multicast routing in place (pimd). 6. Libvirt configured so that it doesn't filter multicast! 7. Tested as working with ssmping Actual results: Packet won't get beyond the first host as the corosync packet has a TTL of one (local subnet). Expected results: TTL should really be 64 for the address range corosync is using. Additional info: This is an old issue from openais days by the look of it: http://www.mail-archive.com/[email protected]/msg00548.html Reply at: https://bugs.launchpad.net/ubuntu/+source/corosync/+bug/637127/comments/4 ------------------------------------------------------------------------ On 2010-09-13T18:19:17+00:00 Neil wrote: Just in case it wasn't clear, each virtual machine has their own 10.x.x.x/30 subnet and there is one on each host Reply at: https://bugs.launchpad.net/ubuntu/+source/corosync/+bug/637127/comments/7 ------------------------------------------------------------------------ On 2011-06-28T10:30:10+00:00 Jan wrote: This is fixed in flatiron d3b983953d43dd17162be04de405d223fb21cd26 and will be included in 1.4.
