Not a lot of detail here, but when does it fail during the process?
Immediately?  After transferring some of the image?  Right at the end?
Connection reset by peer sort of sounds like there is a firewall or something in
the way, although if it transfers some data before crashing, then it's probably
something else.  The only other thing I can think of based on your command-line
below is something to do with your -net options; I've only successfully migrated
with -net tap before, I've never tried -net user.
