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.,

David
