Hyper-V integration components update for Windows virtual machines that are running on a Windows 10-based host
This article describes an update for the latest integrated components for Windows virtual machines (VMs) that are running on a Windows 10-based or Windows Server 2016-based host, or a Windows Server 2012 R2-based host. This update is available on Windows Server 2012 R2, Windows Server 2012, and Windows Server 2008 R2 Service Pack 1 (SP1)-based Hyper-V guest. Before you install this update, check out the Prerequisites section.
Issues fixed in this update
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.
You can get this update through Windows Update and the Microsoft Download Center. Even though this issue has only been observed in Windows Server 2012 R2, Windows Server 2012, or Windows Server 2008 R2 SP1, the update also applies to Windows 8.1 and Windows 7 SP1.
