Adding and Managing VM Devices
Using the Create Virtual Machine wizard configures at least one disk and NIC, and optionally a CD-ROM and display as part of the process, but you can add more devices to suit your use case. Go to Virtual Machines, then click anywhere on a VM entry to expand it and show the options for the VM.
Advanced Settings Screen
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, NTS servers, allowed IP addresses, isolated GPU device(s), self-encrypting drives, and global two-factor authentication.
Isolating GPU for VMs
Systems with more than one graphics processing unit (GPU) installed can isolate additional GPU device(s) from the host operating system (OS) and allocate them for use by a virtual machine (VM). Isolated GPU devices are unavailable to the OS and for allocation to applications.

Virtual Machines
The Virtual Machines screen allows users to add, edit, or manage virtual machines (VMs) or VM devices in TrueNAS. The No Virtual Machines screen shows when there are no VMs configured in or deleted from TrueNAS.
