Perhaps it may make more sense to tweak the code to look at the Make variable
instead and match on "VMware, Inc." which should be the same regardless of what
ends up being reported for the Model information based on BIOS/EFI choice.
To me, that would still fall in line with the KISS principle.

Subject: RE: [MDT-OSD] RE: VMWare EFI VMs Not Seen as Virtual Machines
Sorry, I got sidetracked at work.
I tested both a BIOs VM as well as an EFI VM in VMWare Workstation 12. I ran
“wmic computersystem get model” on each.
BIOs
[cid:image007.jpg@01D2213B.1E66B400]
EFI
[cid:image008.jpg@01D2213B.1E66B400]
Looking at the ZTIGather script this block of code is what sets the “IsVM”
variable for VMWare machines.
ElseIf oEnvironment.Item("Model") = "VMware Virtual Platform" then
' VMware detected
sVMPlatform = "VMware"
bIsVM = true
So because the EFI machines reports back the model as “VMware7,1” it doesn’t
meet any of the criteria for identifying VMs and is then considered a physical
machine. Like Michael said, “…. Knowing VMWare…..”.
I believe that by adding the following to ZTIGather it will be able to catch
these EFI VMs.
ElseIf oEnvironment.Item("Model") = "VMware7,1" then
' VMware detected
sVMPlatform = "VMware"
bIsVM = true
Of course you could get fancy and have it look for “VMware” in the model, but
1) that’s not how Microsoft has written the other VM checks and 2) personally I
like to keep to the K.I.S.S. principle.
Thanks

Are both of the VMs using UEFI? We’ve seen different results from VMware BIOS
vs. VMware UEFI. And knowing VMware, it wouldn’t surprise me if there were
even more ways to tweak it…
Thanks,

Something has changed, but I don’t think it’s the VM. I copied an existing
Task Sequence in SCCM to test UEFI and Server 2016 deployments. My original TS
that’s been working for literally years has this WMI query when determining VM
or physical:
select * from Win32_ComputerSystem where Model like '%Virtual%'
My copied TS didn’t work the first time through and I ran into the same thing,
same ESX VM I’ve used for testing for years, now reports the model like yours
Mike. A quick look at WMI from winpe*10* using wmic:
wmic computersystem get model
Returns
Model
VMware7,1
But if I run the same command on a 2012 R2 esx vm on the same cluster running
the same hardware version it returns
Model
VMware Virtual Platform
The reason I used %virtual% was because I could detect either an esx vm or a
hyper-v vm with that, because hyper-v returns
Model
Virtual Machine
I can’t use just the one WMI query anymore to determine virtual or not if I use
a win 10 PE boot wim.
So Windows is the difference here. “8” code base vs “10” code base that
returns different data for the same WMI entry on the same hardware.
In my experience.

MDT ZTIGather.wsf will try to determine isVM by reading the Make/Model in the
firmware.
Specifically what does: “Get-WMIObject Win32_ComputerSystem” return from
Powershell ( or “wmic computersystem get Manufacturer,Model” ) from within the
Virutal Machine?

Sorry. Having a DUH! morning today.
It’s VMWare Workstation 12.1.1.
My bad.

What specific VMWare environment? We have tested on VMWare Workstation 10 and
11 without issue. We have tested on eSX 5.0 and 5.5 without issue as well.

Subject: [MDT-OSD] VMWare EFI VMs Not Seen as Virtual Machines
Just a heads up. I ran into this problem this morning trying to build a VMWare
VM as EFI.
The task sequence variable “IsVM” is not set correctly. IsVM is set to “false”
so logic we have in our build to bypass things like TPM management on VMs does
not work.
[cid:image010.jpg@01D2213B.1E66B400]
If the VM is set to BIOs then the variable IsVM is set properly.
