Symptoms
VMware 映像層級備份可能會間歇性失敗,並出現類似下列的快照建立錯誤:

在事件檢視器中,應用程式紀錄可能會顯示以下卷影複製服務 (VSS) 錯誤:
Cause
從 Hyper-V 遷移到 VMware 的 Windows VM 會將 Hyper-V VSS 提供者保留在虛擬機器的 Windows 作業系統中:
當 VMware 附掛程式嘗試靜止 Windows 虛擬機器 (VM) 以獲得應用程式一致的快照時,它可能會使用 Hyper-V 提供者。Microsoft軟體卷影複製提供程式應為預設提供程式。
Resolution
若要檢查 Windows VM 上是否仍存在 Hyper-V VSS 提供者,請開啟 PowerShell 提示字元並執行下列命令:
vssadmin list providers
如果輸出中出現「Hyper-V IC Software Shadow Copy Provider」,則可能會導致 VSS 發生問題。
在 Windows VM 上搜尋名稱「regedit」,以開啟登錄。刪除參考 Hyper-V 提供者的註冊表項:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VSS\Providers\{74600e39-7dc5-4567-a03b-f091d6c7b092}]
@="Hyper-V IC Software Shadow Copy Provider"
"Type"=dword:00000002
"Version"="1.0.0.0"
"VersionId"="{c797fff9-2c3e-453c-a3e9-cc7673a6c732}"
刪除登錄機碼後,請將 Windows VM 重新開機,然後重新執行 PowerShell 命令。產生的輸出應顯示 Hyper-V VSS 提供者現已消失。
