SCENARIO - vgimportclone_vdo_using_existing_vg_name:  Create a vdo volume on a VG where and then vgimportclone that VG using the current existing name (bug 2168703) 

Creating VG on grant-01.6a2m.lab.eng.bos.redhat.com using PV(s) /dev/nvme0n1p1 /dev/sdd1 /dev/sde1 /dev/sdg1 /dev/sdh1 /dev/sdc1
vgcreate    vdo_sanity /dev/nvme0n1p1 /dev/sdd1 /dev/sde1 /dev/sdg1 /dev/sdh1 /dev/sdc1
  Volume group "vdo_sanity" successfully created
creating VG on grant-01.6a2m.lab.eng.bos.redhat.com using PV(s) /dev/nvme1n1p1
vgcreate    vdo_sanity1 /dev/nvme1n1p1
  Volume group "vdo_sanity1" successfully created

lvcreate --yes --type linear -n vdo_pool  -L 10G vdo_sanity  
Logical volume "vdo_pool" created.
lvconvert --yes --type vdo-pool -n vdo_lv  -V100G vdo_sanity/vdo_pool
The VDO volume can address 6 GB in 3 data slabs, each 2 GB.
    It can grow to address at most 16 TB of physical storage in 8192 slabs.
    If a larger maximum size might be needed, use bigger slabs.
  Logical volume "vdo_lv" created.
  Converted vdo_sanity/vdo_pool to VDO pool volume and created virtual vdo_sanity/vdo_lv VDO volume.
WARNING: Converting logical volume vdo_sanity/vdo_pool to VDO pool volume with formatting.
  THIS WILL DESTROY CONTENT OF LOGICAL VOLUME (filesystem etc.)
