Dear Community,

I was trying to use the LVM datastore driver [1] and followed the docs
to set it up. 

I have found a "bug" in the docs. oneadmin needs password-less sudo
permissions for:

  * lvremove
  * lvcreate
  * lvs
  * dd
  * *vgdisplay*

vgdisplay(8) is used to monitor [2] the datastore. Without this the
datastore reports 0 size and images cannot be registered.

[1]: http://opennebula.org/documentation:rel4.2:lvm_ds
[2]: 
https://github.com/OpenNebula/one/blob/release-4.2/src/datastore_mad/remotes/lvm/monitor#L59

Good Will,
