"vCenter Converter Standalone" - Feature Requests v22 (25H2) Machines w/ NVMe and OS Detection with Hyper-V Source

[BSeklecki_BOFH]

Is this product (free utility?) under active development?

• When I convert Hyper-V VMs (from Svr2025 Hyper-V), OS Identification doesn't seem to function.  The resulting .vmx has OS type as "Other"
• When I convert Hyper-V VMs (from Svr2025 Hyper-V platform), the resulting disks are "IDE".

However, they need to be NVMe , and OS must be "Windows Server 2xxx" otherwise UEFI boot fails, so I end up using VMWare Workstation 25H2 to convert to a vSphere 8.x compatible machine.

VMX Changes:

Start With:

guestOS = "other"
virtualHW.version = "21"

ide0:0.present = "TRUE"
ide0:0.fileName = "SQL-GOLDEN.usineDor.vmdk"

Instead we want it to produce a VMX with:

guestos = "windows2022srvNext-64" # Or similar

virtualHW.version = "22"

nvme0:0.present = "TRUE"

nvme0:0.deviceType = "disk"

nvme0:0.fileName = "SQL-GOLDEN.usineDor.vmdk"

It looks like in the GUI someone was planning to add the ability to designate the destination HBA/Controller/Disk format, but it's no implemented.

Until then, we can do this PowerShell / sed/awk shell scripting, but the .vmdks still need to be format converted to newer standard I guess too (Haven't researched this)

Thanks.

To add to list:

• I also notice that creates the Virtual NICs as "vlance" (10 mbps) instead of vmxnet3.

 ( I assume that this is because the assumption is that the Hyper-V Guests OSs feature absolute minimum driver support, themselves relying on IDE/ATAPI,  non-Paravirtualized hardware?)

Piling On:

   It seems to create the VMDKs in an older format that are prompted to convert to a new format (Not sure if this corresponds the Machine Version associated with 25H2 or not (virtualHW.version = "22"))

To conclude:

• VMDK Disk Format
• Network: VLANCE => VMXNET3
• Make Guest OS Detection Function
• IDE => NVMe (Optional to force, or accompanying OS Detection)
• Machine Version v22 Compatible
