> {{VMware.pm}} is adding the following to the .vmx file to allow a VM to run
> nested VMs:
> {noformat}
> "monitor.virtual_mmu" => "hardware",
> "monitor.virtual_exec" => "hardware",
> "vhv.enable" => "TRUE",
> {noformat}
> On some hosts, these settings cause the VM to fail to power on. In the VM's
> working directory, {{vmware.log}} contains the following:
> {noformat}
> 2016-07-21T17:04:18.801Z| vmx| I120: Msg_Question:
> 2016-07-21T17:04:18.801Z| vmx| I120: [msg.cpuid.noVHVQuestion] Virtualized
> Intel VT-x/EPT is incompatible with this virtual machine configuration.
> 2016-07-21T17:04:18.801Z| vmx| I120+ Continue without virtualized Intel
> VT-x/EPT?
> 2016-07-21T17:04:18.801Z| vmx| I120: ----------------------------------------
> 2016-07-21T17:04:18.801Z| vmx| I120: MsgIsAnswered: Using builtin default
> '_No' as the answer for 'msg.cpuid.noVHVQuestion'
> {noformat}
> There is no way I have found to override the _msg.cpuid.noVHVQuestion_
> parameter in the .vmx file. If you comment out _msg.autoAnswer_ in the .vmx
> file or set it to false, the following appears in the vSphere Client:
> !ept.png!
> It may be possible to detect whether or not the host will experience this
> problem by querying the _HV Replay Capable_ parameter from _esxcfg-info_:
> {noformat}
> [root@bn17-21:~] esxcfg-info | grep '\-HV Replay Capable'
> |----HV Replay Capable.....................................false
> {noformat}
> On hosts which don't experience this problem, the value is true.
