I have used hardware assisted virtualization in over a year now.
The difference in performance is huge. But last week is stop working.
This is critical as I spend most of my workday in VmWare.
I got a message
VMware Workstation does not support nested virtualization on this host.
Module 'MonitorMode' power on failed.
Failed to start the virtual machine.
If I uncheck checkbox Settings/Processors/Virtualize Intel VT-x/EPT or AMD-V/RVI
the VM starts fine but with slower performance.
So something must have changed!
I suspect a Windows update.
I use VmWare WorkStation Pro 15.5.7 Build-17171714
Host: Windows 10 Enterprise 20H2 64-bit
Guest: Windows 10 Pro 20H2 64-bit
CPU is Intel Core I7 9th generation with 32 GB RAM.
What are my options ?
- First I try to contact support. But it was incredible complicated, Maybe I have to buy support ?
- Upgrade to latest VmWare 16.1 ? I can do that if I am sure it helps.
- I suspect Hyper-V is still active and cause a conflict with VmWare hypervisor. But how do I turn off Hyper-V apart from the obvious in "Turn Windows features off and on" ?
