+===== Configuration de la libvirt =====
+Pour permettre les migrations à chaud, il faut ajouter l'option --listen via  le fichier /etc/sysconfig/libvirtd. Il faut de plus autoriser le tcp, sans le TLS (à voir pour plus tard), ainsi que d'accepter les connexions sans authentification en TCP. Cela se fait dans /etc/libvirt/libvirtd.conf (auth_tcp = none).
