P 2 V Unable to create a VSS Error code 2147754774

VM Forum Team,

        I have attempted on 5 separate attempts to convert a P2V machine using a hot back up ( due to encrypted disk).

Each time it fails with the following error code: FAILED: Unable to create a VSS snapshot of the source volume(s). Error code: 2147754774 (0x80042316)...

I have tried the following remediation steps to accomplish a work around:

  • Selective startup eliminating all non-core services
  • Re-register of VSS components
  • Login of local admin / Run converter as admin
  • Clear registry of sub VSS backup items
  • Disable all antivirus

At this point I am look for any further recommendations.


  • Converter 5.1 - 875114
  • Host OS Win 7 SP1 32 bit on NTFS (w/ Sophos Encryption)
  • Image size 320 GB

Advice would be appricated.. the log is attached to this msg.

* Follow on question, could I use MS backup to create a system image and then convert that to VDMK?*

VSS is Microsoft system component, you should search in msdn forum. Also you should search/ask 'Sophos Encryption' support about this issue.

The Converter will not start P2V task without sucessful snapshot.

Check out the manual about supported 3rd party disk formats.
