As far as I know its only DRS vMotion. We have not had it happen with manual moved
Nothing that I can see related to migration or vmotion has errors. I grabbed every log file from the var directory and did a search for the guest name that was migrating. host.d had the most references. To be honest I am not sure what I am looking for. The only real error I can see about the process is
Delta aborted for virtual machine GUEST-MACHINE host esx-08.domain.corp in cluster esx-08.domain.corp in ha-datacenter: Filter failed
