Yes you are likely right. I should have gone one level deeper in the call
chain. I have not checked all the code paths exhaistively but for the one
I checked, the lowest level functions are indeed reporting the more finer
grained errors to their callers.

I have sent an updated patch that just has the last two hunks. I have kept
virConnectOpenInternal() unchanged.
