As of TrueNAS CORE 13.3, this feature is untested and provided without support to the TrueNAS Community. Users with a critical need to use containers or virtualization solutions in production should migrate to the tested and supported virtualization features available in TrueNAS SCALE. TrueNAS Enterprise customers can contact iXsystems to schedule a TrueNAS SCALE deployment. See CORE to SCALE Migrations for more information.
The Virtual Machines screen displays a list of virtual machines (VM) configured on your system.
Managing Devices After creating a VM, the next step is to add virtual devices for that VM. Using the Create Virtual Machine wizard configures at least one disk, NIC, and the display as part of the process. To add devices, from the Virtual Machines screen, click anywhere on a VM entry to expand it and show the options for the VM.
Click device_hub Devices to open the Devices screen for the VM.
After you download the .iso file, you can start installing TrueNAS SCALE!
This article describes verifying the .iso file and installing SCALE using that file, and selecting the type of installation as either on physical hardware or a virtual machine (VM).
TrueNAS Enterprise SCALE Enterprise customers should receive their systems already installed and ready for UI configuration. If there are any issues with SCALE that requires you to install or re-install SCALE on your TrueNAS server, contact iXsystems Support for assistance.
If you want to access your TrueNAS SCALE directories from a VM, you have multiple options:
If you have only one physical interface, you must create a bridge interface for the VM. If your system has more than one physical interface you can assign your VMs to a NIC other than the primary one your TrueNAS server uses. This method makes communication more flexible but does not offer the potential speed of a bridge.
NPIV (N_Port ID Virtualization) NPIV allows the administrator to use switch zoning to configure each virtual port as if it was a physical port in order to provide access control. This is important in an environment with a mix of Windows systems and virtual machines in order to prevent automatic or accidental reformatting of targets containing unrecognized file systems. It can also be used to segregate data; for example, to prevent the engineering department from accessing data from the human resources department.
Advanced settings have reasonable defaults in place. A warning message displays for some settings advising of the dangers of making changes. Changing advanced settings can be dangerous when done incorrectly. Use caution before saving changes.
Make sure you are comfortable with ZFS, Linux, and system configuration, backup, and restoration before making any changes.
The Advanced settings screen provides configuration options for the console, syslog, audit, kernel, sysctl, storage (system dataset pool), replication, WebSocket sessions, cron jobs, init/shutdown scripts, allowed IP addresses, isolated GPU device(s), self-encrypting drives, and global two-factor authentication.

A virtual machine (VM) is an environment on a host computer that can be used as if it were a separate physical computer.
There are several configuration recommendations and troubleshooting tips when using TrueNAS with a VMware hypervisor.
IQN iSCSI IQN is an acronym that stands for “iSCSI Qualified Name”. It is comprised of the following naming schema with a preamble, node name and unique identifier:
VMware requires using an IQN in their software iSCSI implementation.
Failover A VMware datastore backed by iSCSI-based storage will consist of at least three distinct pieces: the storage host, the switching infrastructure, and the VMware host itself.
The SCALE CLI guide is a work in progress! New namespace and command documentation is continually added and maintained, so check back here often to see what is new!
Use this procedure to create ZFS snapshots when using TrueNAS SCALE as a VMWare datastore.
You must have a paid edition of VMWare ESXi to use the TrueNAS SCALE VMWare Snapshots feature. ESXi free has a locked (read-only) API that prevents using TrueNAS SCALE VMWare Snapshots.
This tutorial uses ESXi version 8.
When creating a ZFS snapshot of the connected dataset, VMWare automatically takes a snapshot of any running virtual machines on the associated datastore.
