Libvirt provides full remote management in its APIs using secure TCP
channels. There is a choice of

  - TLS + x509 certs
  - Kerberos
  - Digest-MD5 (username+password)
  - SSH tunnel + SSH agent

All of these 4 options provide authentication and data encryption of
the sesion. There is more info on the plus & minuses of these here:


I don't recommend using virsh from your webapp - use one of the real
APIs, either C, Python, Perl, OCaml or Java.

provide a large scale web based management UI
