Re: [PATCH 6/8] backup: Add support for passing server socket file descriptor to backup NBD server

From: Peter Krempa <pkrempa(a)redhat.com&gt; In deployments where libvirt is containerized together with the VM it may be hard for the management application to access listening sockets inside the container from the outside. This patch implements "transport='fd'" for the NBD server definition for backups which allows to use the existing "virDomainFDAssociate()" to pass FD to a pre-opened server socket to qemu instead of trying to create it by qemu. Add schema, enable the parser, add formatter and implemet the actual

passing for the qemu backup code.
