Libvirt is only concerned with what virtual hardware you present to the

guest, not with the OS running in that guest or what username/password

combinations will let you log into that guest OS.  libguestfs may be

able to do some introspection for learning usernames, and also has the

ability to create guest clones where you control the usernames and

passwords to be used in the new guest.

  

       Thanks!  so do you mean that I can use libvirt clone a new guest with which I can give username and password?

 

 But it is up to you to manage

your VMs to where you know what username/password pairs are stored for a

given guest image.

      but I've no idea where the username and passwd be stored, create it with dumpXML of a VM, I've tried that original VM's username and passwd via ssh, but it didn't work.
