I can't think of a reason. In fact its a bit warty because we've changed the way we name the instance directories at least once. Its just how this code was written back in the day. Cleaning this up would be a fair bit of work though. Is it really worth the effort just so people can have different

hi Timofei I don't have any specific use case, this issue is found while I am doing live migration testing, what I did is: 1. create 2 compute node, 2. create a nfs service on one of compute node, let's say node-2 and expose /opt/stack/date/nova/instances 3. mount
