VMDK to VHD - Invalid File Format

Postby jjohnson » Mon Oct 08, 2012 4:12 pm

I have copied a VMDK from a VMWare ESXi datastore that I want to convert to VHD. The VMWare virtual guest was shutdown prior to the copy from the ESXi host. When I try to run the Starwind V2V converter it says Invalid File Format (10) [0] . Then on the line below that it says Desciptor is too large. Can anyone tell me what I need to do in order to successfully convert a guest from VMWare ESXi to Hyper-V?

Hello,

The reason of the issue is that we do not support this format yet.

Stay tuned.

Please explain that.....you say you don't support that format. The main description of the program is to convert from VMDK to VHD. This is a VMDK file that I am trying to convert; but you say it is not supported?

For anyone who searches this forum looking for an answer to this I would like to let you know if have finally solved the issue. After downloaded the VMDK file from vSphere I ended up with two .VMDK files. One file was only a few hundred KB while the other was multiple GB. The multi GB sized file has -flat as part of the file name. Since the -flat file is so large I assumed that was the file that I needed to point the Starwind V2V program to in order to convert it to VHD. That was a faulty assumption on my part. Today I tried pointing the Starwind V2V program to the smaller file and it worked perfectly. My lack of VMWare knowledge lead to a faulty assumption. Nevertheless, it works great now.

So, for anyone in the future that might stumble upon this post hopefully this can save you some time. When doing an export from ESXi you will get two files; one of them will have -flat as part of the file name. Use the other one to initiate the conversion!

We've got the same problem, but pointing to the small file didn't help - it returns the error: Error opening file (2) [5]. We're using ESXi v5.1. I can't find anywhere that StarWind specifies which versions of ESXi are supported, so maybe 5.1 doesn't work?

so maybe 5.1 doesn't work?

AFAIK - you are correct in this assumption. We will add this possibility but I haven't got any ETA unfortunately.

Is there any update on VMDK to VHD conversion. I am trying to convert the Cloudera CHD4 VMware VM (posted here http://www.cloudera.com/content/support ... &version=4) to Hyper-V VHD format.

Thanks!

Correct Antoly. Unable to successfully convert Cloudera provided VMDK to VHD.

Are you receiving any errors during the conversion or you have difficulties with importing it to Hyper-V?
Also, are you sure that it suppose to work on Hyper-V? I`m asking cause I haven`t found any downloads for MS solution, and I guess that it just wasn`t design to work on it.

I downloaded the VMWare VM and I am trying to convert that VMDK to VHD.

I get below stated error during conversion:
Invalid file format (10) [0]
Not all descriptor fields are present

Thanks!
