I have an lvm partition for each of my openvz virtual machines.  The way 
I organise it is to have a base directory /vz, with subdirectories for 
each machine.  I mount the lvm logical disk for server1 on /vz/server1, 
and then create the virtual machine with "vzctl create --root 
/vz/server1/root --private /vz/server1/private" (plus other options, 
obviously).

If you need multiple lvm partitions in the same virtual machine, I guess 
you mount them within /vz/server1/private before starting the machine - 
though I haven't needed to do that.

I /really/ wish the openvz developers would move beyond kernel 2.6.32 - 
kernal 2.6.33 introduced snapshot merging to LVM which would play 
wonderfully with this setup.

mvh.,
