The sheepdog datastore driver provides OpenNebula with the possibility of using sheepdog based block-devices for VM images instead of the default file form.

This add-on is compatible with OpenNebula 4.12
Password-less ssh access to the sheepdog-nodes.
A working sheepdog cluster is required. (http://sheepdog.github.io/sheepdog/)
There are some limitations:
Libvirt based snapshots (Snapshots-tab in OpenNebula) are not working as expected. A snapshot is created, but you will not be able to use OpenNebula or libvirt snapshot-revert to restore it automatically!
Workaround: Use Storage-Snapshots (Storage-tab in OpenNebula) to create a hot-copy as soon as your VM in suspend-to-disk.
! Create a backup of your system !
- ssh to opennebula management system
