      Hello,

      Version:
      XCP-NG 8.3.0 on an HP DL380 G9

      I'm exporting my vm using this command:

      xe vm-export vm=2129ae0c-a46f-5a07-2d5f-3a9d7d1baf42 filename=/run/sr-mount/a7f6df31-412f-d5e9-4163-8af75b1df8ad/myVMtoExport.xva

      But after few minutes I'm getting this error which is not clear to me
      The server failed to handle your request, due to an internal error. The given message may give details useful for debugging the problem.
      message: Unix.Unix_error(Unix.EIO, "read", "")

      I don't really understand where to look at, in the Xensource logs I have the same message but doesn't give me a clue what could be the issue.
      My VM is working correctly I can start it up and use it normally. So I don't understand where could be the issue.
      I have tested to run this export both with the machine runinng and the machine stopped in both case I have the same issue.
      Xensource logs.

      Any idea that could point in the correct direction or a workaround to backup this VM would be greatly appreciated.

      With kind regards.

        Hi,

        There weren't any other errors / warnings just prior to the Feb 3 00:22:24 entries?

        Have you tried using vhd-cli check to verify the VDI's integrity?
