[systemd-devel] Fedora 25, cgroups V2 and systemd roadmap

[Kevin Wilson]

Hello, Daniel,

This sounds very reasonable, I don't have anything against this policy.

Still, I wonder: are you ruling out implementing "hybrid mode" (like
Lennart uses in systemd) for libvirt? I mean a mode where you will use
the 3 currently supported cgroup V2 controllers for libvirt (memory,
io and pids; actually I don't know if you use the cgroups pids at all
in libvirt, it is a new controller; BTW - do you ? ). And using other
controllers (besides io, memory and pids) from cgroup V1

Regards,
Kevin
