I have the latest version of VMware player (free). I have an OVA that requires VT-x/EPT and am running into this exact issue:
VMware Workstation does not support nested virtualization on this host.
I have a clean, updated version of Windows 10. I'm using the latest version of Player, Hyper-V is disabled. I see a number of people aren't having any luck on workarounds. Any updates?
Welcome to the Community,
please provide some information about your hardware.
Create a VM (e.g. a virtual ESXi host) and enable "Enable VT-x/EPT ..:" on the virtual CPU, then start the VM, and if you see the same error, attach the VM's vmware.log file to your next reply.

According to the log file, Virtualization Technology (VT-x) does not seem to be enabled in your host's BIOS.

Unfortunately it's not detected as enabled. Can you confirm that - after enabling it in the BIOS - that you did a complete power cycle of the host, i.e. complete power off/power on?
What does CPU-Z report?
André
-With virtualization disabled in the bios, cpu-id Instructions shows VT-x. When I try to run the VM, Player errors out saying it needs VT-x. Task manager shows virtualization disabled.
-With virtualization enabled in the bios, cpu-id Instructions does not show VT-x. When I try to run the VM, Player gives my original error. Task manager shows virtualization enabled.
Latest BIOS and firmware. I'm officially confused.
Can you tell me which line of the log shows that VT-x is not enabled?
I'm also experiencing the same issue. I've also included my vmware log as well. I've seen previous thread and have only been able to run my ESXi VM by disabling Hyper-V. Any help on this would be appreciated.

Please run msinfo32.exe to see what it reports for the different "Hyper-V" settings in the system overview screen.
André
The System Summary screen shot doesn't show the Hyper-V settings. Please scroll down on the right side for these settings.
Btw. you can insert images directly into the reply, no need to add them as an attachment.

I think you are faced with the fact that Vmvare Workstation (and the Player) does not support nested virtualization on Windows hosts with Hoper-V support enabled. This situation occurs on Windows 10 2004 and later. Although Vmvare declares that Hoper-V and Workstation can work together, this is not true in terms of nested virtualization. The only solution to use nested virtualization is to disable the Hyper-V boot. See details in the discussion in thread - VMware Workstation does not support nested virtualization on this host.
Hi dude.
well I had the same problem and my Virtualization Technology in my bios setting was the VT-x so I disabled it.and also I turned the hyper-v & virtual machine platform & windows hypervisor platform and after restarting my pc the problem was solved.
I hope this could be useful for you bro!
