The packages are stuck on py3.6 which means they will be pain once we switch to 3.7. Please test them on 3.7 *and* 3.8 (so we don't to revisit this in a few months), and update PYTHON_COMPAT appropriately. If it doesn't work, please either fix it, remove Python or issue last rites. Please consider this urgent.
ping.
I confirm libguestfs works with python3.7. I use it as dependency of LAVA.
Ping, maksbotan can you look at this? We're close to dropping py3.6 support.
Ping, maksbotan - py3.6 support is now dropped (commit: 3b120860ecfa) and it has caused some havoc with world updates. In particular I had to unmask app-misc/hivex-1.3.18 to get world updates working again. I really don't want to see libguestfs get last rites as this package is important/useful when dealing with a lot of virtual machines.
Support for python has been dropped for now, so closing here: https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=34e0d817f35aad31d992a35f436603e3e8eed3bb
