Hello again
This bug is fixed in latest OpenVZ RHEL6 kernel. Actually RHEL6 kernel
is fully supported by OpenVZ team now, it has better performance and a
few new features like vswap. Enjoy.
[root@dhcp-10-30-22-214 /]# cat /proc/self/mountinfo
33 26 0:21 /private/101 / rw,relatime - simfs /vz/private/101
rw,usrquota,grpquota
40 33 0:25 / /proc rw,relatime - proc proc rw
41 33 0:23 / /sys rw,relatime - sysfs sysfs rw
42 33 0:27 / /dev/pts rw,relatime - devpts none rw,mode=600,ptmxmode=000
43 40 0:28 / /proc/sys/fs/binfmt_misc rw,relatime - binfmt_misc none rw
[root@dhcp-10-30-22-214 /]# uname -a

You can use latest RHEL6-based kernel builds on your Debian or Ubuntu
machine. Here's how.
1. Get the latest kernel from either Download/kernel/rhel6-testing or
Download/kernel/rhel6. You need vzkernel and vzkernel-devel packages
only, with the -devel being optional.
2. Install fakeroot and alien:
apt-get install alien fakeroot
3. Convert these two rpms to debs using alien. This is
fakeroot alien --to-deb --scripts --keep-version vzkernel-*.rpm
4. Install debs as usual. Reboot. Enjoy.
dpkg -i vzkernel*.deb
