[one-users] Open Nebula unable to delete the snapshot of a VM

[Italo Madalozo]

Hi Jaime,
thanks for the reply. /images is not a path it is the name of the VG, first
I tried /dev/images and it did not work, when I change to /images it works.
But it can not delete the snapshots afterwards.

Cheers

Italo
