Issue

  • Do Linux kernel's Control Groups (cgroups) feature support CPU hot adding on Virtual Machines like vmware ?
  • Will it recognize added CPU as an available resource and hence can make it available for controlled processes ? Or
  • I do need to reboot the system?

Environment

  • Red Hat Enterprise Linux 8
  • Vmware ESxi host
  • Cgroup version 1 with systemd
