Consider the following scenario:
- You connect a VM to a virtual switch that uses a physical adapter.
- You enable the single-root I/O virtualization (SR-IOV) option in Virtual Switch Manager.
- You disable the physical adapter on the Hyper-V guest while network I/O is running on the VM.
The current Write Ahead Logging (WAL) implementation incorrectly assumes that the Virtual Hard Disk (VHD) ownership never changes. However, the ownership does change in multiple VM group replication in a shared VHD scenario.
