A virtual machine is migrated between two servers. A method, at the first server, dismounts a volume on which all the files relating to the virtual machine are stored, and which was previously mounted at the first server. The method, at the second server, mounts the volume on which all the files relating to the virtual machine are stored, so that the second server can host the virtual machine. In this way, the virtual machine can be migrated without having to copy all the files from the first server to the second server. The files relating to the virtual machine are stored on a storage-area network (SAN).
