[Lxc-users] sched_setscheduler fails in a container (was: Re: Lxc-users Digest, Vol 29, Issue 7)

[Jianbin Ma]

The output of my program is as below:

hp180:/tmp # ./syl
Max priority is 99, min priority is 1
process 15952 policy is : 2 priority is : 33

which indicates the priority is not out of range.And I've also add
cap_sys_nice permission via setcap cmd. But it still not work.


The output of getcap cmd :

vps1:/tmp # getcap syl
syl = cap_sys_nice+ep
