Paolo Bonzini points out that in my refactoring of the code for virDomainMigrate(), I added a check for the return value from virDomainMigratePerform(). The problem is that we don't want to exit if we fail, we actually want to go on and do virDomainMigrateFinish2() with a non-0 return code to clean things up. Remove the check. While reproducing this issue, I also noticed that we wouldn't always properly propagate an error message. In particular, I found that if you blocked off the migration ports (with iptables) and then tried the migration, it would actually fail but we would get no failure output from Qemu. Therefore, we would think we succeeded, and leave a huge mess behind us. Execute the monitor command "info migrate", and look for a failure string in there as well.
