How to active cgroups V1

You can enable cgroups V1 by adding systemd.unified_cgroup_hierarchy=false and systemd.legacy_systemd_cgroup_controller=false as permanent parameters of the kernel. In order to that follow these instructions:

• Open the GRUB file:

  sudo nano /etc/default/grub
  

• Add to GRUB_CMDLINE_LINUX_DEFAULT the two parameters:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash systemd.unified_cgroup_hierarchy=false systemd.legacy_systemd_cgroup_controller=false"

• Update grub:

  sudo update-grub
