    Junos Space Virtual Appliance Deployment Overview

    The Junos Space Virtual Appliance is distributed in the Open Virtualization Appliance (OVA) and qcow2 formats.

    You can deploy the Junos Space Virtual Appliance *.ova file on a VMware ESX server version 4.0 or later or VMware ESXi server version 4.0 or later and the *.qcow2 on a Kernel-based Virtual Machine (KVM) server. The Junos Space Virtual Appliance Release 16.1R1 and later can be deployed on qemu-kvm (KVM) Release 1.5.3-105.el7 or later which is on CentOS Release 7.2.

    Note: Though a KVM server on other Linux distributions is supported, we recommend that you use KVM on CentOS.

    After the Junos Space Virtual Appliance is deployed, you can use the VMware vSphere client or Virtual Machine Manager (VMM) to connect to the VMware ESX (or VMware ESXi ) server or KVM server respectively and configure the Junos Space Virtual Appliance.

    Note: Where the Junos Space Virtual Appliance documentation references “ESX server,” you can use either the VMware ESX server version 4.0 or later or VMware ESXi server Version 4.0 or later.

    The minimum hardware requirements for deploying a Junos Space Virtual Appliance are as follows:

    • 64-bit quad processor with a clock speed of at least 2.66 GHz
    • Four virtual CPUs
    • 1-Gbps Network
    • 32-GB RAM to configure the virtual appliance as a Junos Space node or fault monitoring and performance monitoring (FMPM) node

      Note: 64-GB RAM is required if the number of rules per firewall (SRX) cluster is more than 6000 and if firewall policies of similar sizes are being concurrently published.

    • 500-GB hard disk
    • Configure Open VM tools


    • We recommend that you use disks with I/O speed of 200 Mbps or above. For information about determining I/O speed of a disk used in the node of a Junos Space cluster, see How do I Determine the Disk I/O Speed of a Node in the Junos Space Fabric? in the Junos Space Hardware and Virtual Appliances FAQ.
    • We recommend against cloning a deployed Junos Space Image and using it as another instance of a Junos Space Virtual Appliance.
    • VMware VMotion is not supported for moving Junos Space Virtual Appliances from one VMware ESX server to another VMware ESX server.
