Error creating VM - TrueNAS 12.0 - U2

[abnexus]

I made the migration over to TrueNas Core 12 recently and going through and correcting various things from FreeNAS 11 setup. I'm having an error with creating a Ubuntu Desktop VM (version 20.04.2). Any thoughts what I'm possibly overlooking? UEFI boot is turned on in the BIOS.

System Specs
CPU: AMD Ryzen 5 2600 Six-Core Processor
Threads: 12
Memory: 16gb

VM setup specs:
Virtual CPUs: 3
Cores: 3
Threads: 6
Memory: 3072 MiB
Space 100 Gb

The answer seems to be in the question...

You're trying to ad 3 VCPUs with 3 cores each, with 6 threads per core, so 3x3x6=54 threads

Reduce your numbers to something resulting in less than 16 just like it says.

Some serious Overprovisioning !
