[v2v PATCH v2 0/3] Use libosinfo for query device drivers
by Pino Toscano
This patch series integrates libosinfo in virt-v2v to get the list of
files for Windows from libosinfo, if possible. The actual data is still
from virtio-win, just unpacked.
Changes from v1:
- adapt to use the priority in libosinfo 1.7.0+
- filter out non-pre-installable drivers
- collect all the drivers matching the requirements, not just the first,
sorting them by priority like libosinfo does to get the best ones
- actually upload the files by the lowercase file name
- few minor fixes
Pino Toscano (3):
build: require libosinfo
v2v: add a minimal libosinfo interface
v2v: try to get windows driver files from libosinfo

[v2v PATCH 1/2] Add back guestcaps as parameter of output#prepare_targets
by Pino Toscano
It will be used to do extra checks in the output before copying the
disks.
Partially revert commit 3bafec4e693a25ef1c84abc0fd1bc3251862c7de.
