Why libvirt mount /sys/fs/cgroup/* inside container as rw ?
We use kernel 3.10.0-693.2.2.el7.x86_64 and XFS and therefore our
containers are privileged. Yes, we know that in such containers root
can use SysRq at least for reboot hardware node. But problem with
cgroups can be more hidden and cryptic.
p.s.2
we still use libvirt-3.0.0, if it's important.
