Yeah, you are masking another problem.  The problem is that this portion
of migration is running on the destination of the migration, and generating
a string that the source of the migration will use to perform the migration.
By passing the 1 flag to virGetHostnameLocalhost, you are allowing it to
return "localhost" as the string.  This means that when the source tries
to migrate, it will actually try to migrate to "localhost", not the
destination, and fail in complicated-to-debug ways.

The actual problem you have is that the "hostname" command on your
machine is returning a string that resolves to localhost, probably because of
a misconfiguration in /etc/hosts.
