Can't enable vmtools timesync

[rkbennett]

SUMMARY

When attempting to set the tools.timeSync value for enabling vmware tools time synchronization changes are never actually made When using the vmware_guest module placing the configuration in advanced_settings makes no change:

advanced_settings:
  - key: tools.syncTime
    value: 'TRUE'

I've also tried adding it under customvalue, which causes the task to fail from an unknown key

Does the module report a change that doesn't happen, or doesn't it even do that and report that everything's OK?

[rkbennett]

It shows it in the invocation, and the task completes fine, but it doesn't actually get set on the vm.

[mariolenz]

Is this some kind of "magic" or "protected" setting? I can neither see nor set it through the UI (vCenter 7.0.3d). The same with PowerCLI:

PS C:\Users\mario> $vm = Get-VM -Name "synctest"
PS C:\Users\mario> Get-AdvancedSetting -Entity $vm -Name "tools.syncTime"
PS C:\Users\mario> New-AdvancedSetting -Entity $vm -Name "tools.syncTime" -Value "TRUE" -Confirm:$false -Force:$true

I always see a task in vCenter that completes just fine, but the time synchronization isn't changed at all. So I think this isn't really a problem of the vmware_guest module, you just can't configure this advanced setting directly imho.

[rkbennett]

Well, reading the description of advanced_settings, IIRC it says that it can set values within the vmx file, which tools.syncTime is located in. That is why I was attempting it through that method

You're right, advanced_settings should be able to set an advanced setting like tools.syncTime. However, it looks like the vSphere API doesn't allow this. The module can add or change other advanced settings without any problems.

That said, I don't think this is a bug in the module. But I think it's a valid feature request to be able to enable timesync via VMware Tools somehow.

[msilveirabr]

Indeed, it looks like a "magic setting". I don't know how Hashicorp Packer deals with advanced/custom settings, but it has a dedicated config param for timesync in vsphere-iso plugin.

For now, I'm managing to enable timesync using vm_shell:

[mariolenz]

I don't think we should implement this in vmware_guest, the module is already far too complicated.

Maybe a new module vmware_tools_config? We could start with implementing syncTimeWithHost and syncTimeWithHostAllowed, but could also add other settings from ToolsConfigInfo there when the need arises.
