Re: [libvirt] [RFC PATCH 2/4] qmp/hmp: Add getfd_file monitor command

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'?
