Hi all,

as I mentioned already yesterday I get this error when I try to start the
OpenVZ service:

[root@s10b10-0 ~]# /etc/init.d/vz start
Starting OpenVZ: [ OK ]
Bringing up interface venet0: [ OK ]
Configuring interface venet0: [ OK ]
vzctl set 0 --cpuunits 1000 failed: Setting CPU units: 1000
fairsched_chwt: No such file or directory
WARNING: Settings were not saved and will be resetted to or[FAILED]alues on
next start (use --save flag)

I tried the latest kernels 2.6.18 and 2.6.20 with CONFIG_SCHED_VCPU=y and
CONFIG_FAIRSCHED=y
For both kernels the vzctl command ends up with the same error.

Can someone explain me why it is searching for a file or directory? Is
fairsched_chwt a device?

Mit freundlichen Grüßen / Best Regards
Christian Kaiser

Can you check the value of __NR_fairsched_chwt in vzctl? It is defined
in include/vzsyscalls.h depending on your architecture. For ppc it
should be 402 (same as in kernel's include/asm-powerpc/unistd.h). In
case these numbers are different things will go wrong.

You can easily check it the number using strace, like this:
# strace vzctl set 0 --cpuunits 1000 2>&1 | grep syscall

I checked on that. The same value 402 defined in both header-files.

[root@s10b10-0 ~]# strace vzctl set 0 --cpuunits 1000 2>&1 | grep syscall

no output and without the grep pipe:

[root@s10b10-0 ~]# strace vzctl set 0 --cpuunits 1000

I guess you have to use strace64 or smth like this.
