Hi all,
I did my first steps wtih OpenVZ on a JS21 Blade. I'm running FC6 and built
my own 2.6.18 kernel from kernel.org with your latest patches (028stab31).
I used the default kernel config (not yours but from vanilla kernel) and I
removed support for checkpointing. There was no menu entry for the Fair CPU
scheduler in the menuconfig for the powerpc architecture. The compilation
failed printing the following lines:
In file included from drivers/media/video/pwc/pwc-uncompress.c:29:
include/asm/current.h: In function ‘get_current’:
include/asm/current.h:23: warning: implicit declaration of function
‘offsetof’
include/asm/current.h:23: error: expected expression before ‘struct’
make[4]: *** [drivers/media/video/pwc/pwc-uncompress.o] Error 1
make[3]: *** [drivers/media/video/pwc] Error 2
make[2]: *** [drivers/media/video] Error 2
make[1]: *** [drivers/media] Error 2
make: *** [drivers] Error 2
Then I replaced the include/asm/current.h file with the
include/asm/current.h file of the vanilla kernel and compiled for new. Now
it works. I could compile and boot the kernel with your patches (excluding
the include/asm/current.h file).
After that I installed the ppc64 rpm packes of vzquota, vzctl and
vzctl-lib. "vzkernel" and "vzquotamod" were missing so I had to force the
installation (--nodeps) because I did the kernel compilation on my own,
right?
After installation I tried to run /etc/init.d/vz start but it faild because
of a missing library libvzctl-0.0.2.so. I found it in /usr/lib64 instead of
/usr/lib.
[root@s10b10-0 ~]# /etc/init.d/vz start

vzctl set 0 --cpuunits 1000 failed: /usr/sbin/vzctl: error [FAILED]ading

It seems to be that there is a mixture of 32 and 64 bit binaries and libs.
See that output of /usr/sbin:

another error when starting /etc/init.d/vz start

What is "fairsched_chwt"? And why is it missing in my configuration?? An VE
creation works fine:
[root@s10b10-0 cache]# vzctl create 101 --ostemplate
debian-3.1-powerpc-minimal --ipadd 192.168.0.101 --hostname ve101

VE private area was created
but starting an VE fails. There is no verbose output on that even when I
switch it on.
[root@s10b10-0 ~]# vzctl --verbose start 101

VE start failed

[root@s10b10-0 ~]#
Can someone help me on this?

related to Fair CPU scheduler:
please check that CONFIG_SCHED_VCPU=y
then CONFIG_FAIRSCHED will appear and should be set to y as well.
You are right, CONFIG_CPT should be disabled as powerpc is not supported by
checkpointing currently.

imho, it is a mainstream bug (maybe triggered by our changes).
2 fixes possible:
1. Simply add:
#include <linux/stddef.h>
in include/asm-powerpc/current.h (after #include <asm/paca.h>)
2. or add the same line at the very beginning at file which failed to compile,
i.e. to drivers/media/video/pwc/pwc-uncompress.c

this changes came from diff-merge-2.6.18.8-20070227, which is essentially
the fixes from 2.6.18.8. i.e. the following changeset from mainstream caused the problem:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.1 8.y.git;a=commitdiff;h=f102c840f7f72492a83c93fa65396fe0edcf1df6

looks like all binaries from vzquota package are 64bit, while
binaries from vzctl package are 32bit... Can you try to recompile vzctl yourself please?
and please tell me where you took the binaries from so I could recheck/fix it if needed :)

looks like you have 32bit binaries in vzctl since configure script didn't add
-m64 to CFLAGS, though it has a code in configure.ac for this.
Checking...

vzctl should be compiled with -m64 flag to gcc. There is a code in
configure.ac for that:
if test x$build_cpu = xppc64; then
CFLAGS="${CFLAGS} -m64"
fi
So it looks like in your case $build_cpu is set to something different
than 'ppc64' -- can you tell us its value so we can fix this
configure.ac code accordingly?
As a workaround, you may do
CFLAGS="-m64" ./configure
make clean
make

Christian,
sys_fairsched_chwt() can return ENOENT in the only case:
when fairsched node ID was not found in the list.
but VE0 node is always on the list.
So I guess there is something wrong with syscall args in your case.
Please apply the attached patch to the kernel and vzctl
recompile/reboot and report the output of both.
Thanks,
Kirill

OK! here it is:
1. vzctl:

Setting CPU units: 1000
vzctl: fairsched_chwt(2147483647, 500)

That's it! Yeah!
/etc/init.d/vz start seems to work without errors. I was able to start an
VE and to enter it. I will do a more precise testing next week.
Thank you very much and please add the patch to the git repository of
2.6.18-openvz!

Here I am back from testing. Creating, starting and stopping a VE works
great. Then I did testing with LTP syscall Testing Suite on a native JS21
Blade and then inside a VE (with all capabilities except syspcap) that I
created from a selfmade FC6-ppc template.
Unfortunately some tests fail already on the native running FC6 with Kernel
2.6.18-028stab033:
swapon02, vmsplice01
And these tests fail inside a VE:
syslog12, ustat01, ustat02 + the two tests I mentionned above.
That means that the same tests fail inside a powerpc64 VE like in a x86 VE.
Thats a great effort, I guess, because we could say that OpenVZ runs
"stable" on powerpc64. Now I'll try to find out why these two tests fail
when they run natively.

Hi Kirill,
imho there is no reason for not adding the patch to the git repository.
I've tested it for one week now and I'm getting no serious errors.
