stoney conductor: VM States

Naming of VM states (the second state is only needed for special cases).

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    

No.	Status	Run Action				Action						Explanation
		Start	Shutdown	Power Off	Migrate	Edit	Delete	Toggle Boot-Drive	Use	Create persistent VM	Create dynamic VM
1	Stopped							x		x	x
2	Stopped, streaming	-	-	-	(x) <ref name="TechnicalClarificationNeeded"/>	(x) <ref name="RestrictionsRequired"/>	-	x	-	x	x	After clicking "+" a list of all the vms (sstDisplayName) should appear with [5.1 %].
3	Stopped, backing up
4	Stopped, migrating											Same state for the vm being migrated to a node and away from a node.
5	Stopped, first installation											If sstVirtualMachineMode is set to first installation.
6	Stopped, maintenance mode											If sstVirtualMachineMode is set to maintenance mode.
7	Starting											Technically changing state from stopped to running.
8	Paused, backing up											Technically migrating to file.
9	Paused, migrating											The vm is being migrated to this node.
10	Running
11	Running, backing up											Technically merging, retaining, streaming.
12	Running, migrating											The vm is being migrated away from this node.
13	Running, first installation											If sstVirtualMachineMode is set to first installation.
14	Running, maintenance mode											If sstVirtualMachineMode is set to maintenance mode.
15	Shutting down
16	Powering off
17	Deleting
18	Do not use											If sstVirtualMachineMode does not exist.
