It has been observed that chipset.motherboardLayout is automatically changed to "acpi" in the VMX file when provisioning a virtual machine via the Content Library, even if the VM template contains chipset.motherboardLayout = "i440bx".
From the VM template,
| $ grep chipset *.vmtx chipset.motherboardLayout = "i440bx" |
From the Virtual Machine deployed via the Contents Library,
| $ grep chipset' *.vmx chipset.motherboardLayout = "acpi" |
VMware vSphere ESXi 8.0
The content library doesn't preserve chipset.motherboardLayout property while cloning the VM template to the Content Library as OVF file.
This issue will be addressed in the future release.
