for the most part i mount them on boot. i have one guest that i dont want
mounted until i use it, so i have a special script i run when i want to use
that guest which mounts the lvm mount point then calls vserver to start the
guest so the mount point is visible in the host until i stop the guest, then
the script unmounts it after stopping the guest. its just a specialized init
script.
