Okay - but why do you want to do that? Do you have different hard drives?

I don't understand that. What's that supposed to show? hda3 and
then something about a Primary LogVol? I don't get it.

I don't understand.

You said, you want to  dual boot linux/linux. In this case, I'd 
create *ONE* Volume Group. I'd make this VG out of just ONE Physical
Volume /dev/hda2.

In the VG, I'd then create Logical Volumes as necessary.

Suppose you'd install Fedora Core 5 and Ubuntu, I'd create the
following LVs:

- FC5Root
- FC5USR
- FC5Var
- FC5Opt

- UbuntuRoot
- UbuntuUSR
- UbuntuVar
- UbuntuOpt

- Home
- Swap

I'd actually name them EXACTLY this way.
