SymptomsWhen I’m migrating a physical server to a Virtual Environment (VE) using the P2V migration tool, I get the following error message:
Operation migrate_p2v with the VE(s) VEID777 from 188.8.131.52 to VE#777 is finished with errors: #3401 P2V migration failed : SWAHaulControlOperator with id ‘ vzlinmigrate_p2v_serializer' stage 'SetActiveVolumes' failed : Failed to create snapshot.
I see the following error in Event Viewer on physical host:
Event Type: Error
Event Source: VolSnap
Event Category: None
Event ID: 41
Description: When preparing a new volume shadow copy for volume C:, the shadow copy storage on volume D: did not have sufficiently large contiguous blocks. Consider deleting unnecessary files on the shadow copy storage volume or use a different shadow copy storage volume.
CauseLikely the reason is due to a shortage of disk space.
Currently, the p2v migration tool operates in the following manner:
1. Installs the SWagent on the remote physical server.
2. Performs a VSS(Volume Shadow Copy) copy.
3. Transfers the shadow copy to the Virtuozzo node.
4. Creates a VE for this copy.
5. Restores the shadow copy restore inside the newly created VE.
Based on the error message, the problem occurs during the second step outlined above.
