[Libvir] [PATCH]Reprt error for a existing file

Hi,

I tried to put xen community, it rejects.

Though I am understanding follwing, 
Isn't there something good way ?

If this goes on, for user managing services by using virsh/libvirt,
there is no way to recover for the user.

For example, save file(maybe used as backup file) is overwritten 
without any confirmation, I suspect that user confuses about the 
one different from expected OS starting.

Surely, although it is a user's mistake, I want to solve this by 
saying a confirmation like a below, so that user can confirm it once.

  # virsh save <domain> <file>
    save: save file  "<file>"?
  #

  # virsh dump <domain> <file>
    dump: dump file "<file>"?
  #

How do you think about this?
