Set-VM change ConfiguredGuestID and Configured Guest OS

[nlong12]

Good morning!

Looking for a way to change via set-vm configuredguestid and configured guest OS.  It appears after pawing through help text there is no set-vm cmdlet or option which could be used to change the values.   Is this correct, am i missing something?   It appears the vm must be powered off in order to change the  Configured Guest OS.  Here is the script I'm fiddling with:

Get-Content -Path D:\PowerShell_temp\Configured_GuestId.txt | %{

Get-VMGuest -VM (Get-VM -Name $_) | Set-VM -ConfiguredGuestId centos6_64Guest -Confirm:$false

  }

Thank you in advance for your input.

Not sure why you are using Get-VMGuest.

You can do

Get-VM -Name MyVM | Set-VM -GuestId windows9_64Guest

The values you can use on the GuestId parameter are defined in the VirtualMachineGuestOsIdentifier enum.

Hi Lucd;

Trying to change Configured GuestID and Configured Guest OS don't have a need to change GuestID, hence the need to use Get-VMGuest -VM    if I'm understanding correctly the only way I can  access ConfiguredGuestID  is through Get-VMGuest,  your right but it doesn't appear one can change the Configured Guest OS via set-vm

Thanks for your input

What you name Configured GuestID is changed with the command I gave above.

In fact the ConfiguredGUestID property is the same as the GuestID property.

Get-VM | Select Name,

   @{N='ConfiguredGuestId';E={$_.Guest.ConfiguredGuestId}},

   @{N='GuestID';E={$_.ExtensionData.Config.GuestID}}

Not too sure what you mean with the Configured Guest OS.
Where do you see that property?

Hello Lucd;

I'm looking at our vcheck report in the section titled "Virtual machines with incorrect OS configuration" columns 4 "Configured GuestID" and column 5 "Configured Guest OS"

Ok, got you.

The change can be done with

Get-VM -Name fwapp261 | Set-VM -GuestId centos6_64Guest

What the vCheck report shows as Configured  Guest OS is in fact the name of the guest OS, as determined by the VMware Tools.

You can't change that value, unless you reinstall a new guest OS.

Hello Lucd;

Understand your command but for some reason it's not working

Here is a snippet from vcheck report

Name GuestId Installed Guest OS Configured GuestId Configured Guest OS

FwApp261

centos6_64Guest

CentOS 6 (64-bit)

rhel6_64Guest

Red Hat Enterprise Linux 6 (64-bit)

Note the following opportunity:

1:58 PM]ndl@FWTS012:Powershell_Test $ Get-VM -Name fwapp261 | Set-VM -GuestId centos6_64Guest

Set-VM : 9/10/2018 2:07:39 PM Set-VM The guest operating system 'centos6_64Guest' is not supported on the host.

At line:1 char:25

    + FullyQualifiedErrorId : Client20_VMServiceImpl_TryValidateGuestId_UnsupportedGuestId,VMware.VimAutomation.ViCore.Cmdlets.Commands.SetVM

Should I assume the host refers to the esxi host the VM is assigned to, any thoughts as to why this message is occuring

Thank you for your patience!!!

The range of supported guest OS depends also on the version of the ESXi node on which you run the VM.

That's what the error message also seems to suggest.

Which ESXi version are you using?

[nlong12]

Hello Lucd;

Our current version is 6.5.0

Norm

[LucD]

That is strange, since the centos6_64Guest guestid is supported since 6.5.

See also the VirtualMachineGuestOsIdentifier enum I mentioned earlier.

Is that 6.5 for the ESXi nodes and the vCenter?

Is the VM powered off when you run the script?
