VMware Snapshots
VMware snapshot integration allows TrueNAS to coordinate ZFS snapshots with VMware datastores.
Accessing NAS from VMs and Containers
If you want to access your TrueNAS directories from within a virtual machine or container hosted on the system, you have multiple options:
Allow TrueNAS to create an automatic bridge (default).
Manually create a bridge interface if you have only one physical interface.
Assign a NIC other than the primary one your TrueNAS server use if you have more than one physical interface. This method makes communication more flexible but does not offer the potential speed benefits of a bridge.
Configuring Virtualization and Apps
Configuring TrueNAS to work with virtualized features, such as virtual machines (VMs) and applications, is part of the setup process that, when optimized, takes advantage of the network storage capabilities that TrueNAS offers.
This article assumes you have the latest release version of TrueNAS installed on your system. The following steps are a list of configuration prerequisites you have completed and are familiar with before beginning VM and application installations.
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.
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, NTP servers, allowed IP addresses, isolated GPU device(s), self-encrypting drives, and global two-factor authentication.
