Re: [ANNOUNCE] Sheepdog: Distributed Storage System for KVM

We use JGroups (Java library) for reliable multicast communication in
our cluster manager daemon. We don't worry about the performance much
since the cluster manager daemon is not involved in the I/O path. We
might think about moving to corosync if it is more stable than
JGroups.
