I did: "/etc/init.d/vz start" with vpsid 101 and 109, which from:
http://bb.xnull.de/projects/gentoo/amd64/stage4-amd64-current.tar.bz2
following the guide from:
http://www.gentoo.org/proj/en/vps/openvz-howto.xml

Didn't change the content of stage4-amd64-current.tar.bz2 yet.
It looks like when "/etc/init.d/vz start", it will cp all files from
/vz/private/101/ to /vz/root/root/101/

The oops allways reproduced yesterday between reboot and kernel
remake, but this morning when I trying to finger out the oops point
using strace, I can't get the oops anymore. Sorry for interrupt,:-(

Maybe distcc caused problem? I used to make kernel... Sorry again.
