It appears I have spoken too soon after more I am still seeing issues with omping in some circumstances. When I use omping from a host somewhere else on the same network to a VM on the KVM host I am seeing packets getting duplicated. The duplicate packet issue was present in 2.4 and earlier and was fixed in 2.5.
