The libvirt code base exposes all of these migration schemes (although it currently favors fd: migration wherever possible). Starting a migration requires a Unix socket on the monitor command, and passing in the file descriptor via SCM_RIGHTS via the 'getfd' monitor command prior to using the 'migrate' monitor command to use that new fd. --=20 Eric Blake eblake@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org --------------enig570F2BA497A3901FA4E76DC0 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) Comment: Public key at http://people.redhat.com/eblake/eblake.gpg Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBCAAGBQJQBDM/AAoJEKeha0olJ0NqYyYH/2bJr6W/StmLbcvZbVGCRZBT i+TqUCSIBB4BKLrk2+Hfkp9lc2uDs5YBKv7obIpGMf/niTB3rqyoohinvZ+K8iiz 03gXSG1hjvxI6jZ+EdsXDUBqd/FqkmBJCPmxWKxnuhqi5UqkBSGnSFaDN75o3o1h TpYLKhDAuc/UOa2rOISNq8IYnaduuYcw1ACiQ/iznZY2tkCdKdWbxSdKWIhakjw9 I+kCiwcBuN5A5wdL7baQki5lso7Ub5D/yexBfakbzsyqoImXdkrrURGpOY+O4KRE cVeIvADwylampfG//eTUbdscZ3EPtZl1Tm17a9q2K/NK51DrU3MEOugA3/G8RzA= =HZzH -----END PGP SIGNATURE----- --------------enig570F2BA497A3901FA4E76DC0--
