Virtual Machines States Reference

This page is a complete reference of all the VM states that will be useful for administrators doing troubleshooting and developers.

The simplified life-cycle is explained in the Managing Virtual Machines guide. That simplified diagram uses a smaller number of state names. These names are the ones used by onevm list, e.g. prolog, prolog_migrate and prolog_resume are all presented as prol. It is intended as a reference for end-users. That section should be enough for end-users and every-day administration tasks.

List of States

In OpenNebula a Virtual Machine has 2 variables to define its state: STATE and LCM_STATE. The LCM_STATE is only relevant when the STATE is ACTIVE. Both states can be seen from the CLI (onevm show) and from Sunstone (Info panel for the VM).

Note

LCM_INIT state is used as LCM_STATE when the VM is in a state different than ACTIVE.

#	State	#	LCM State	Short State Alias	Meaning
0	INIT			init	Internal initialization state right after VM creation, this state is not visible for the end users. And hence this state cannot be used to hook any action.
1	PENDING			pend	By default a VM starts in the pending state, waiting for a resource to run on. It will stay in this state until the scheduler decides to deploy it, or the user deploys it using the onevm deploy command.
2	HOLD			hold	The owner has held the VM and it will not be scheduled until it is released. It can be, however, deployed manually.
3	ACTIVE	0	LCM_INIT	init	Internal initialization state, not visible for the end users
		1	PROLOG	prol	The system is transferring the VM files (disk images and the recovery file) to the host in which the virtual machine will be running.
		2	BOOT	boot	OpenNebula is waiting for the hypervisor to create the VM
		3	RUNNING	runn	The VM is running (note that this stage includes the internal virtualized machine booting and shutting down phases). In this state, the virtualization driver will periodically monitor it
		4	MIGRATE	migr	The VM is migrating from one host to another. This is a hot migration
		5	SAVE_STOP	save	The system is saving the VM files after a stop operation
		6	SAVE_SUSPEND	save	The system is saving the VM files after a suspend operation
		7	SAVE_MIGRATE	save	The system is saving the VM files for a cold migration
		8	PROLOG_MIGRATE	migr	File transfers during a cold migration
		9	PROLOG_RESUME	prol	File transfers after a resume action (from stopped)
		10	EPILOG_STOP	epil	File transfers from the Host to the system datastore
		11	EPILOG	epil	The system cleans up the Host used to virtualize the VM, and additionally disk images to be saved are copied back to their datastores
		12	SHUTDOWN	shut	OpenNebula has sent the VM the shutdown ACPI signal, and is waiting for it to complete the shutdown process. If after a timeout period the VM does not disappear, OpenNebula will assume that the guest OS ignored the ACPI signal and the VM state will be changed to running, instead of done
		15	CLEANUP_RESUBMIT	clea	Cleanup after a delete-recreate action
		16	UNKNOWN	unkn	The VM couldn’t be monitored, it is in an unknown state
		17	HOTPLUG	hotp	A disk attach/detach operation is in progress
		18	SHUTDOWN_POWEROFF	shut	OpenNebula has sent the VM the shutdown ACPI signal, and is waiting for it to complete the shutdown process. If after a timeout period the VM does not disappear, OpenNebula will assume that the guest OS ignored the ACPI signal and the VM state will be changed to running, instead of poweroff
		19	BOOT_UNKNOWN	boot	OpenNebula is waiting for the hypervisor to create the VM (from UNKNOWN)
		20	BOOT_POWEROFF	boot	OpenNebula is waiting for the hypervisor to create the VM (from POWEROFF)
		21	BOOT_SUSPENDED	boot	OpenNebula is waiting for the hypervisor to create the VM (from SUSPENDED)
		22	BOOT_STOPPED	boot	OpenNebula is waiting for the hypervisor to create the VM (from STOPPED)
		23	CLEANUP_DELETE	clea	Cleanup after a delete action
		24	HOTPLUG_SNAPSHOT	snap	A system snapshot action is in progress

		26	HOTPLUG_SAVEAS	hotp	A disk-saveas operation is in progress
		27	HOTPLUG_SAVEAS_POWEROFF	hotp	A disk-saveas operation (from POWEROFF) is in progress
		28	HOTPLUG_SAVEAS_SUSPENDED	hotp	A disk-saveas operation (from SUSPENDED) is in progress
		29	SHUTDOWN_UNDEPLOY	shut	OpenNebula has sent the VM the shutdown ACPI signal, and is waiting for it to complete the shutdown process. If after a timeout period the VM does not disappear, OpenNebula will assume that the guest OS ignored the ACPI signal and the VM state will be changed to running, instead of undeployed
		30	EPILOG_UNDEPLOY	epil	The system cleans up the Host used to virtualize the VM, and VM files are transferred to the system datastore
		31	PROLOG_UNDEPLOY	prol	File transfers after a resume action (from undeployed)

6	DONE			done	The VM is done. VMs in this state won’t be shown with onevm list but are kept in the database for accounting purposes. You can still get their information with the onevm show command
8	POWEROFF			poff	Same as suspended, but no checkpoint file is generated. Note that the files are left in the host to later boot the VM there. When the VM guest is shutdown, OpenNebula will put the VM in this state
9	UNDEPLOYED			unde	The VM is shut down. Similar to STOPPED, but no checkpoint file is generated. The VM disks are transferred to the system datastore. The VM can be resumed later
10	CLONING			clon	The VM is waiting for one or more disk images to finish the initial copy to the repository (image state still in lock)
11	CLONING_FAILURE			fail	Failure during a CLONING. One or more of the images went into the ERROR state
