I have a Dell Precision 7560 i7-1185H, 32G of RAM. I enabled virtualization in the BIOS.
However, when trying to launch a VM (GNS3, EVE-NG) for networking labs, I have this error message:
And when I click Yes, the error is below and the VM fails to start
So, I had to uncheck this option in the VM's option for it to start:
The VM does start, but with this warning
I believe having that option uncheck will lower the performance. When I start a couple of equipment in an Eve-NG lab (Router, Switch..), the CPU usage goes up drastically. The process name is vmware workstation vmx.
I'm using vMware Workstation 16 Pro.
I do need help, and I'd be very grateful if I get any.
As your post needs moving to the area for Workstation, I have reported it to the moderators.
Workstation will use Hyper-V as an hypervisor instead of the VMware hypervisor if Hyper-V is enabled in Windows. You can verify this if you look in the vmware.log file of the VM and search for the line containing "Monitor Mode:". If it's "ULM", then Workstation is using Hyper-V.
Nested virtualization can't be done if this is the case. This is a Hyper-V restriction as Microsoft hasn't provided a way for third-party virtualization solutions to do it. Certain features of Windows like virtualization based security and memory integrity also use Hyper-V components, which interfere with nested virtualization.
Try the advice in https://communities.vmware.com/t5/VMware-Workstation-Pro/VMware-Workstation-does-not-support-nested-... to disable Hyper-V and related components so that Workstation can use the VMware hypervisor.
