Create LVM Volume on Blockdevice

That's odd behavior, don't think that should happen.

I am not entirely sure but I think that's possible, yes. I just ran 
pvcreate /dev/sda in a test environment and created a VG and LV on top 
of it just fine.

That, too, should be possible. I think you need (at least) the lvm grub 
module.

it appears that everything you want is possible but setup-storage 
doesn't support it, yet. I'll try and implement a solution for your 
usecase in the upcoming days.
