[lug] How do I mimic the Fedora and SuSE installer's feature of creating LVMs with the xubuntu installer?

If you want to understand LVM, you should read the LVM Howto. Then get 
at least 2 extra hard drives for practice. Then learn to use the command 
line LVM tools. THEN do it with the installer. Otherwise, trust me, you 
will spin your wheels. Plus when you "get it" using the command line 
utils, it will make using the installer understandable and not a pain in 
the ass.


P.S. Your error is because you didn't create any physical volumes before 
creating a volume group. An LVM volume group is made up of physical 
volumes (i.e. hard drive partitions, hardware RAID volumes, Software 
RAID arrays, etc).
