Windows 10 VM Blue Screen MULTIPROCESSOR_CONFIGURATION_NOT_SUPPORTED

[jstockley2020]

Recently I tried to create a windows 10 vm on FreeNAS-11.3-U3.2. After booting to the virtual cd drive I get a blue screen error saying "MULTIPROCESSOR_CONFIGURATION_NOT_SUPPORTED". I have 2 ubuntu vms working perfectly fine. I have even tried to turn them off to see if that would resolve the problem with no luck. My CPU is a AMD FX(tm)-4100 Quad-Core Processor with 24GB of ram. I also have 2 3tb drives with an ssd for caching. If you need any additional information please let me know.

Thanks
Jack

How many cores have you assigned to your Windows VM?
Set the loader tunable hw.vmm.topology.cores_per_package to at least that number so your VM will see only a single package.

You need to rebbot your FreeNAS for the setting to become effective.

Try setting these loader tunables to reflect your CPU:

Code:

hw.vmm.topology.cores_per_package=4
hw.vmm.topology.threads_per_core=2

These take effect on reboot.
