  • Question

  • Hi,

    In our environment we have a Windows 10 virtual machine which resides on server 2019 hyper-v server.
    We are taking backup of this virtual machine through DPM server which is also installed on a virtual machine.

    An error is logging constantly on hyper-v server which is as below..

    Failed to map guest I/O buffer for write access with status 0xC0000044. Device name = E:\Hyper-V\Win10-06\Virtual Hard Disks\Win10-06.vhdx

    I'm unable to find a satisfying answer for this error.

    Is there anyone who can help us regarding this issue?

    Thanks.
