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
