This thread touched an old pain point, so I might have gotten carried away a bit.

Please confirm these settings are enabled in the BIOS of your MSI B450 motherboard:
> AMD-V - the AMD Virtualization equivalent to Intel VT-x (this 'should' also enable Extended Page Tables (EPT).
> If EPT is NOT enabled by the AMD-V settings then search further in BIOS.
> Secure Virtual Machine (SVM) in BIOS. - Also, this might need to be enabled. I'm not familiar with that motherboard.
Some interesting posts specific to nested virtualization and AMD Ryzen. Please read. Lots of good info.
Welcome to VMware Workstation Pro™ documentation. Use the navigation on the left to browse through documentation for your release of VMware Workstation Pro. We update the online documentation with the latest point release information. For example, version 14 contains all the updates for 14.x...

You can configure processor settings for a virtual machine, including the number of processors, the number of cores per processor, and the preferred execution mode for the virtualization engine.

I'll like to configure a new AMD build and like to know or nested VM's possible with a 3xxxX AMD proc (TRX-40 with AMD 3960x) within VMware Workstation Pro 15. My current (old) Intel build has no problem with nested VM's within VMware Workstation Pro 15. I'll have read it does have something to...

Hello to all, I'm trying to build my own home lab for VMware solution testing, mainly to learn about the technologies and how to get arround them (install, configure, manage kind of stuff). My setup is as follows: CPU: AMD Ryzen 1700X, MB: Asrock X370 Taichi UEFI 4.80, 64 GB RAM, Windows 10 Pro...

The next section might 'sound' preachy or condescending. I do not intend it as so.
Merely offering advice to better enjoy your journey.
RANDOM ACCESS MEMORY - YOU CAN DO MORE with MORE
If your situation allows, install AT LEAST another 16 GB more RAM for total of 32 GB on your system.
General virtualization NEEDS lots of memory, the more the better.
Also, I read stories of people running small amounts of RAM with ZFS (8 GB or 4 GB). Yes the OS and ZFS might run ok ... BUT ZFS will run better and enable you to use more of its features if more RAM is installed. In my opinion, fast RAM is more important than a fast processor. I've seen slow processors with ample RAM do more work than much faster processors with insuffcient RAM. Processors have ALWAYs been faster than RAM memory. Processors can eat more data faster than memory can feed. That is why we have CACHES ... level 1, level 2, level 3 in modern processors... built with the same silicon and on same chip. The processor is hungry and most of the time sits idling ... relaxed ... smoking a cigarette or eating bags full of Dorito bits.
If you're into lots of games ... GREAT ... a fast processor and graphics processor, help alot. However, when venturing away from gaming to do virtualization or enable great data integrity features of great filesystems (yes ZFS), fast RAM becomes king. So, if virtual machines and enterprise type filesystems appeal to you, then please add more memory to your current setup.
WHY NESTED VIRTUALIZATION ?
Why does nested virtualization appeal to you? Is there a specific goal to achieve or constraint to overcome?
Nested virtualization sounds cool and IS amazing that it works ... at all ... but for stable development, testing, evaluation, ... well maybe, but probably not. The word 'maybe' is being generous. For a production system that serves customers, the answer is emphatically, NO !
"Danger, Will Robinson !!"
NO CHANGE, NO PAIN, NO GAIN
Next, if you are open to change ... willing to reconfigure your system disk to gain performance, operational stability, and easier troubleshooting ... then consider two alternate suggestions for your personal setup:
(1) Dual Boot Windows & TrueNAS (a nicely tailored FreeBSD with bhyve virtualization)
Backup your system disk, backup your personal settings and all important data. Wipe system clean = erase ... everything.
Install a boot manager on the system disk and allocate space for each Windows & TrueNAS. In a past life, Microsoft OS installers often trashed existing partition tables of other previously installed OS types. To avoid that, install the Microsoft OS ...first. Finally, install TrueNAS. This setup will run faster, and safer, than the Microsoft OS + VMware WS + TrueNAS with bhyve + whatever virtualized OS combination (This is similar to a House of cards?). Then after some sweaty gaming, reboot system, select TrueNAS (FreeBSD in a nicely tailored dress shirt & trousers) + Bhyve to run cool virtual machines.
(2) Dual Boot Windows & VMware ESXi
This ALSO runs faster than the Microsoft OS + VMware WS + TrueNAS with bhyve + whatever virtualized OS ... house of cards.
On your hardware, MSI B450 motherboard, ESXi requires a third party network driver for network to function.
Here is an example:
https://networkguy.de/installing-realtek-driver-on-esxi-6-7/
Why a third party driver? Because ESXi prefers Intel network devices and consequently will not work since the
MSI B450 motherboard has a RealTek 8111H GLAN.
Now via ESXi, install TrueNAS as a virtual machine. This nested virtualization just might work. I've not tested this combination, so I disclaim any guarantee. You might get lucky.
That is all.
Constructive criticism welcome.
