This patch provides support for the getfd_file monitor command. This command will allow passing of a filename and its corresponding file descriptor to a guest via the monitor. This command could be followed, for example, by a drive_add command to hot attach a disk drive.

Is the only difference between 'getfd' and 'getfd_file' the fact that 'getfd' introduces an abstract namespace usable only by the fd: protocol, while the 'getfd_file' introduces a name identical to the absolute naming of the file system and usable by the file: protocol? What happens if I pass 'getfd_file' a relative file name? Must the filename passed to 'getfd_file' be in canonical form, or may it contain symlinks, .., and other non-canonical constructs? Can the 'closefd' command be used to close the fd originally given to qemu via 'getfd_file'? -- Eric Blake eblake@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
