Naming of VM states (the second state is only needed for special cases). The following attributes need to be read:
- sstStatus: Located directly in virtual machine leaf.
- sstProvisioningMode: Located in the virtual machine backup sub tree(s).
See the descriptions in the document stoney conductor: OpenLDAP directory data organisation in the chapter Virtual Machine and Virtual Machine: Backup for details.
Virtual Machines
Naming of VM states (the second state is only needed for special cases), valid for VMs:

Possible future states:
- Crashed (when vm should be running, but there isn't a QEMU process around)
- Frozen or Non responding (requires QEMU guest agent or a watch dog)
Future editing:
- Certain values like disk, cpu and memory will be able to be changed, even if the vm is running.
Tool-Tips:
- "stopped, streaming (without the percent status)": Show streaming information with vm-name(s) and percent status.
- Save text of Tool-Tips in language files.
VM Templates
Naming of VM states (the second state is only needed for special cases), valid for VM Templates.
Since VM Templates are basically VMs with additional metadata and can be cloned from, most of the runtime states are the same as for VMs and therefore not explicitly copied below and the respective entries are shaded .
