原来devstack 没有创建vg ，手动创建vg如下

执行truncate -s 15G vg_file

root@map-VirtualBox:/etc/cinder# losetup -f --show vg_file
/dev/loop0

root@map-VirtualBox:/etc/cinder# vgcreate stack-volumes-lvmdriver-1 /dev/loop0
  No physical volume label read from /dev/loop0
  Physical volume "/dev/loop0" successfully created
  Volume group "stack-volumes-lvmdriver-1" successfully created

查看vg
