Our team intends to let users use virsh as a part of the our team product.
Therefore, it is not kind of to let users use redirection.
When users use virsh, and an error occurred, our team wants to investigate
it without letting users take trouble.

Because this patch cannot gather information of virterror yet,
I plan to add the file output processing to error handler.
