The Virtualization section allows users to set up Virtual Machines (VMs) to run alongside TrueNAS. Delegating processes to VMs reduces the load on the physical system, which means users can utilize additional hardware resources. Users can customize six different segments of a VM when creating one in TrueNAS SCALE.

TrueNAS assigns a portion of system RAM and a new zvol to each VM. While a VM is running, these resources are not available to the host computer or other VMs.

TrueNAS VMs use the KVM virtual machine software. This type of virtualization requires an x86 machine running a recent Linux kernel on an Intel processor with VT (virtualization technology) extensions or an AMD processor with SVM extensions (also called AMD-V). Users cannot create VMs unless the host system supports these features.

To verify that you have Intel VT or AMD-V, check your processor model name on the vendor’s website. If needed, enable virtualization in the BIOS Advanced > CPU Configuration settings.
