I’ll be listing common errors you may come across using Microsoft virtual machine converter. This is a powershell tool you can use to convert files such as a virtualbox or vmware vm file. This link gives a very good overview of the tool https://wyliebayes.com/convert-most-ova-virtual-machines-to-vhd-or-vhdx-with-powershell-for-use-with-hyper-v/ . FYI if this is an OVA file you need to first extract it, this will then extract the vmdk file, which is what you will convert.
The entry is not a supported disk database entry
If your getting this error it means the file descriptor in the file isn’t being recognized.
- To fix this download and extract the dsfok tool https://www.mysysadmintips.com/-downloads-/Windows/Servers/dsfok.zip Next run dsfo.exe with syntax as such
.\dsfo.exe "pathtovmdkfile" 512 1024 "pathtovmdkfolder\descriptor.txt"
- Open descriptor.txt in Notepad. comment out the line the error mentions for example I had the error below. and uncommented this line below.
- Save VMDK descriptor back
.\dsfi.exe "pathtovmdkfile" 512 1024 "pathtovmdkdescriptorfile"
- Try running converto-mvmcvirtualharddisk again. If it fails repeat steps 1-3, commenting out error line.
