I don't think this needs to be documented in the manpage. It's
poweruser enough that users can figure it out on the command line via
--disk help output. So please drop this bit
For new options I'm trying to get closer to the libvirt XML naming, so
it's more discoverable and predictable. So I'd like the command line
ot be
--disk
reservations.managed=no,reservations.source.type=unix,reservations.source.path=/tmp/pr-helper0.sock,reservations.source.mode=client
For virt-install, I want to drop the reservations.source.type,
reservations.source.path and reservations.source.mode as well,
only support "--disk reservations.managed=yes", Would you agree?
Thanks for your review,
Lin
