[Libguestfs] [PATCH v2 0/4] v2v: simplify driver copying from virtio-win iso

Libguestfs supports passing an ISO image as a source of virtio windows drivers to v2v. That support, however, looks too heavy-weight: in order to access those drivers, a separate guestfs handle is created (and thus a new emulator process is started), which runs until v2v triggers garbage collection. This series attempts to make it simpler and lighter-weight, by making the relevant code more local, and by hot-adding the image into the main guestfs handle if supported by the backend. Roman Kagan (4): v2v: consolidate virtio-win file copying v2v: copy virtio drivers without guestfs handle leak v2v: drop useless forced gc v2v: reuse main guestfs for virtio win drivers iso --- changes since v1: - rebased to latest master (in particular, updated usage of string functions) - add missing and remove excessive parentheses - reorder patches - preserve support for backends with no hot-add capability v2v/convert_windows.ml | 206 ++++++++++++++++++++++++++--------------------- v2v/utils.ml | 212 +++++++++++++++---------------------------------- v2v/v2v.ml | 8 -- 3 files changed, 179 insertions(+), 247 deletions(-) -- 2.4.3
