    Release Information

    Statement introduced in Junos OS Release 12.3.

    Description

    Describe the basic attributes a virtual machine (VM) needs as a VM instance. These attributes are called virtual machine descriptors. An instance description is used to deploy and instantiate a virtual machine. The description is configured using the Junos CLI. The user specifies on which compute node a VM will run and what resources are allocated to it.

    The virtual machine management (VMM) infrastructure allows for pre-provisioning. You can configure a VM instance without the compute nodes being physically present in the network. When the nodes are available, the virtual machines are instantiated based on policy and configuration. Any change in VM configuration will result in restart of the VM before the changed configuration takes effect.

    Options

    instance instance-name

    Name of the VM instance.

    cpu cpu-number

    (Optional) Number of CPUs assigned to the VM.

    (Optional) Memory for the VM, in gigabytes.

    Default: 1

    Range: 1 to 32; do not configure more than 16 GB for a VSE 1100 tethered device
