First you have to create a physical volume, for example pvcreate 
/dev/xvdb1. Now you can assign this physical volume to a new volume 
group by using vgcreate nova-volumes /dev/xvdb1.

If you haven't installed lvcreate, vgcreate, .. do it with apt-get 
install lvm2.

You can find more details here:
