[Freeswitch-users] OpenVZ tuning tips

Fri May 24 09:30:32 MSD 2013

Hello,

Thank you for tips, we are testing centos/openvz 6 with 2.6.32 kernel on
host and Ubuntu 10.04 LTS in VE.
Do you know maybe how to allow realtime priority in the VE for FS? Running
FS with -rp does not set the scheduler.
strace says, sched_setscheduler operation permitted, so SCHED_FF is not
set. Tried to run as root and/or use ulimit -r option, but cannot run FS
with tuned priorities.We guess, some thing missing in the host/VE
configuraton.
Any idea?

Br,
  Tamas
