COMMANDS

· create [file] Creates a new VM from the given description instead of using a
previously defined template (see ´onetemplate create´ and ´onetemplate instantiate´).

Examples:

- using a template description file:

onevm create vm_description.tmpl

- new VM named "arch vm" with a disk and a nic

onevm create --name "arch vm" --memory 128 --cpu 1 --disk arch \
--network private_lan

- a vm with two disks

onevm create --name "test vm" --memory 128 --cpu 1 --disk arch,data
valid options: multiple, hold, name, cpu, vcpu, arch, memory, disk, nic, raw, vnc, vnc_password, vnc_listen, spice, spice_password, spice_listen, ssh, net_context, context, boot, files_ds, init, dry

· update vmid [file] Update the user template contents. If a path is not provided the
editor will be launched to modify the current content. valid options: append

· delete range|vmid_list Deletes the given VM. Using --recreate resubmits the VM.

Resubmits the VM to PENDING state. This is intended for VMs stuck in a
transient state. To re-deploy a fresh copy of the same VM, create a
Template and instantiate it, see ´onetemplate instantiate´

States: ANY
valid options: schedule, recreate

· hold range|vmid_list Sets the given VM on hold. A VM on hold is not scheduled until it
is released. It can be, however, deployed manually; see ´onevm deploy´

States: PENDING
valid options: schedule

· release range|vmid_list Releases a VM on hold. See ´onevm hold´

States: HOLD
valid options: schedule

· disk-snapshot vmid diskid img_name Sets the specified VM disk to be saved in a new
Image. The Image is created immediately, but the contents are saved only if the VM is
shut down gracefully (i.e., using ´onevm shutdown´ and not ´onevm delete´)

If ´--live´ is specified, the Image will be saved immediately.

States: ANY
valid options: type, live, clonetemplate

· shutdown range|vmid_list Shuts down the given VM. The VM life cycle will end.

With --hard it unplugs the VM.

States: RUNNING, UNKNOWN (with --hard)
valid options: schedule, hard

· undeploy range|vmid_list Shuts down the given VM. The VM is saved in the system
Datastore.

With --hard it unplugs the VM.

States: RUNNING
valid options: schedule, hard

· poweroff range|vmid_list Powers off the given VM. The VM will remain in the poweroff
state, and can be powered on with the ´onevm resume´ command.

States: RUNNING
valid options: schedule, hard

· reboot range|vmid_list Reboots the given VM, this is equivalent to execute the reboot
command from the VM console.

The VM will be ungracefully rebooted if --hard is used.

States: RUNNING
valid options: schedule, hard

· deploy range|vmid_list hostid [datastoreid] Deploys the given VM in the specified
Host. This command forces the deployment, in a standard installation the Scheduler is
in charge of this decision

States: PENDING
valid options: enforce

· migrate range|vmid_list hostid Migrates the given running VM to another Host. If used
with --live parameter the miration is done without downtime.

States: RUNNING
valid options: enforce, live

· boot range|vmid_list Boots the given VM.

States: UNKNOWN, BOOT
valid options: schedule

· stop range|vmid_list Stops a running VM. The VM state is saved and transferred back to
the front-end along with the disk files

States: RUNNING
valid options: schedule

· suspend range|vmid_list Saves a running VM. It is the same as ´onevm stop´, but the
files are left in the remote machine to later restart the VM there (i.e. the resources
are not freed and there is no need to re-schedule the VM).

States: RUNNING
valid options: schedule

· resume range|vmid_list Resumes the execution of the a saved VM

States: STOPPED, SUSPENDED, UNDEPLOYED, POWEROFF
valid options: schedule

· recover range|vmid_list Recovers a stuck VM that is waiting for a driver operation.
The recovery may be done by failing or succeeding the pending operation. YOU NEED TO
MANUALLY CHECK THE VM STATUS ON THE HOST, to decide if the operation was successful or
not.

Example: A VM is stuck in "migrate" because of a hardware failure. You
need to check if the VM is running in the new host or not to recover
the vm with --success or --failure, respectively.

States: Any ACTIVE state.
valid options: success, failure

· disk-attach vmid Attaches a disk to a running VM. When using --file add only one DISK
instance.

States: RUNNING
valid options: file, image, target, cache

· disk-detach vmid diskid Detaches a disk from a running VM

States: RUNNING

· nic-attach vmid Attaches a NIC to a running VM. When using --file add only one NIC
instance.

States: RUNNING
valid options: file, network, ip

· nic-detach vmid nicid Detaches a NIC from a running VM

States: RUNNING

· chgrp range|vmid_list groupid Changes the VM group

· chown range|vmid_list userid [groupid] Changes the VM owner and group

· chmod range|vmid_list octet Changes the VM permissions

· resched range|vmid_list Sets the rescheduling flag for the VM.

States: RUNNING

· unresched range|vmid_list Clears the rescheduling flag for the VM.

States: RUNNING

· rename vmid name Renames the VM

· snapshot-create range|vmid_list [name] Creates a new VM snapshot valid options:
schedule

· snapshot-revert vmid snapshot_id Reverts a VM to a saved snapshot

· snapshot-delete vmid snapshot_id Delets a snapshot of a VM

· list [filterflag] Lists VMs in the pool valid options: list, delay, filter, csv, xml,
numeric, kilobytes, describe

· show vmid Shows information for the given VM valid options: xml, all

· top [filterflag] Lists Images continuously valid options: list, delay, filter, csv,
xml, numeric, kilobytes

· resize vmid Resizes the capacity of a Virtual Machine (offline, the VM cannot be
RUNNING) valid options: cpu, vcpu, memory, enforce, file
