  • 1.  VMware Workstation 25H2 - esxi as guest - vm failed to start

    Posted 12 days ago

    I'm currently trying to set up an ESXi guest for a test environment in VMware Workstation 25H2. When selecting 'VMware ESX' as the guest operating system under Options and choosing any version, starting the VM with VT-x enabled fails with the error message 'Failed to start the virtual machine.' However, if the guest operating system is changed to Microsoft Windows, the VM starts successfully. The host system is Windows 11 25H2.

    Ok, the culprit was the enabled Credential Guard of Windows 11 25H2. After disabling the CG and a reboot the ESXi hosts are running with the correct Guest operating system option. This CG is a pain in the ass
