      What were you trying to do that didn't work?

      Choose the Windows Failover Cluster (WSFC ) that owns the shared disk.

      Execute IO on the shared disk and keep it running.

      Live-migrate the node to another host.

      The PR is migrated, but the IO in the node has failed due to "Resource Temporarily unavailable"

      wait aboult 1 minute, rerun the io it may be successful.

      How reproducible is this bug?:

      100%

      Steps to reproduce

      1. Boot Domain nodes 
        virsh start start vm-msdomain
        virsh start start vm-msnode1
        virsh start start vm-msnode2
        (The domain and cluster is build finished)
      1. Access the node that owns the shared disk
      2. Execute io on the disk
        c:\win_io.bat
      3. live migration of the node to another host
        virsh migrate --live vm-msnode1 qemu+ssh://root@vmx3/system --verbose
      4. Check the io in the node
      5. Check the io in the host
        IO error on the source host
        IO succeeds on the target host

      Expected results

      Step 4 no affect

      Actual results

      step 4 io error exit
