TANSTA a lowest spec.

The hardware should just support Linux 2.2 or 2.4 including LVM ;-)

The only constraint is RAM which must be decently sized, because LVM keeps
metadata in the kernel.

If you play around with LVM test configurations and for eg. choose to have
*small* PE sizes you could eventually end up with large LVM mapping tables
leading to low memory.

Nevertheless the LVM driver checks for this and prevents you from loading
such amounts of metadata; IOW: you wouldn't be able to activate your VG(s)
or create/extend your LVs in this case and LVM still shouldn't crash on you.

    Nevertheless it needs not so stupid people to solve them ***
