I read through the page covering NFS server inside a container:
http://wiki.openvz.org/NFS_server_inside_container

I have a host running the following kernel (Debian Squeeze):

root@cluster-02:~# uname -a
Linux cluster-02 2.6.32-5-openvz-amd64 #1 SMP Sun May 6 05:21:56 UTC 2012
x86_64 GNU/Linux

The kernel modules are loaded and I can export filesystems from the host
and mount them on remote hosts.
I am trying to create a VE where I can run the NFS server, but I can not
get this to work properly.

Inside the VE, I get the following when I try to start the NFS server:

root@fs01:/# /etc/init.d/nfs-kernel-server start
FATAL: Could not read
'/lib/modules/2.6.32-5-openvz-amd64/kernel/fs/nfsd/nfsd.ko': No such file
or directory
Not starting NFS kernel daemon: no support in current kernel. ... (warning).

This is the output when I install nfs-kernel-server:

Only RHEL5 and 6 based kernels support nfsd in CT. See
http://wiki.openvz.org/Install_kernel_from_RPM_on_Debian_6.0

(warning).

Apparently it tries to load kernel module. Kernel module is already loaded
(on the host system). Plus, there are no kernel modules files inside CT.

I guess you have to modify the script to skip trying to install kernel
module.
