[pve-devel] qemu-server : remove openvz fairscheduler cpuunits

[Alexandre DERUMIER]

>>seem also that cgroups are not working with lxc currently.

Seem that it's need a daemon called "cgmanager"  (systemctl start cgmanager)

https://linuxcontainers.org/cgmanager/introduction/


When the daemon is running, starting an lxc container create an

 /sys/fs/cgroup/systemd/lxc/vmid/  entry

seem also that cgroups are not working with lxc currently. 

Trying to add 

lxc.cgroup.cpu.shares = 100 

in a lxc container config, 
I don't see any entry in /sys/fs/cgroup/

I think It should be easy to implement cgroups in qemu-server, like libvirt is doing 
https://libvirt.org/cgroups.html 

I think we use same code for lxc and qemu (I need to dig a little more)

first, we need -id for authentication (pve-auth.patch). 
Also, if we implement cgroups inside pve-qemu-kvm, we can keep this code. 
Or do you think it is easier to implement cgroups inside qemu-server?
