Virtualized Intel VT-x/EPT is not supported error

[ShadowTiger95]

I am trying to operate a GNS3 Virtual machine on VMWare Workstation 17 and I need that option selected in the Processor's settings in order for it to fully work.  Please tell me any and all solutions that may help.

Assuming you are running a Windows 10 or 11 host operating system, you may need to totally disable Hyper-V to allow the native VMware hypervisor to work.

Search the forum for information on how to disable Hyper-V in Windows. It involves removing all Hyper-V Windows components, disabling Virtualization Based Security and Memory Integrity features, and setting the hypervisorlaunchtype off via bcd edit.
