This article describes an issue that occurs in a Windows 8.1 or Windows Server 2012 R2 Hyper-V host. A hotfix is available to resolve this issue. Before you install this hotfix, check out the Prerequisites section.
Introduction
Consider the following scenario:
-
You have a Windows Server 2012 R2-based computer that is configured for one or more NIC teams by using Windows NIC Teaming (LBFO).
-
You have implemented Windows NIC Teaming (LBFO) in Switch Independent teaming mode by using Hyper-V Port or Dynamic Load Balancing mode. Additionally, you have correctly configured the NICs to use non-overlapping processors. (For more information, see Knowledge Base article 2974384).
-
A Hyper-V virtual switch is bound to one of the LBFO teams.
-
You start a virtual machine on the Hyper-V server, or you live migrate a virtual machine from one server to another server.
In this scenario, you experience one or more of the following issues:
-
Issue 1: The following Error 113 event is logged intermittently in the event log:Log Name: SystemSource: Microsoft-Windows-Hyper-V-VmSwitchDate: <DateTime> Event ID: 113Task Category: NoneLevel: ErrorKeywords:User: SYSTEMComputer: Server1.contoso.comDescription:Failed to allocate VMQ for NIC EDCED345-4C96-4C75-92A0-0C4FC5688F73--35BEB899-5BE9-4128-900A-6FE0BBFC7B22(Friendly Name: Network Adapter) on switch DE4F3664-68D9-4781-825B-882A540FAB08 (Friendly Name: VM Switch).Reason - The OID failed. Status = {Operation Failed} The requested operation was unsuccessful. Additionally, the Hyper-V VmSwitch may fail to allocate VMQ queues for virtual machines.Note In the event description, the Reason text is always "The OID failed." The Status text varies based on the network adapter driver that is being used. Other Status examples include the following:
-
Status = An invalid parameter was passed to a service or function
-
Status = Insufficient system resources exist to complete the API
-
Status = Unknown
Cause This issue occurs because the VmSwitch assumes that the default processor for VMQ is zero (0) when it performs VMQ allocation. This causes some network adapter drivers to reject the allocation and generate Error 113.Fix information After you apply this hotfix, the VmSwitch no longer assumes that the default processor for VMQ is zero (0).For more information about this issue, see Knowledge Base article 3001783.
-
-
Issue 2: Performance degrades or the system stops responding.Cause This issue occurs because LBFO physical resource mapping algorithm overloads the host. This issue can also trigger "MAC flapping."Fix information After you apply this hotfix, the rebalancing algorithm is optimized and made more scalable.
-
Issue 3: A STOP 0xD1 error occurs on the host during live migration. Cause This issue occurs after LBFO clears its own structures because it assumes that the forward progress of the Object identifier (OID) is guaranteed. Fix information After you apply this hotfix, LBFO clears its mappings only if the OID succeeds. For failure scenarios, LBFO passes the OID status back to VmSwitch. VmSwitch receives the failure status and processes it through its own logic.
Resolution
Hotfix information
A supported hotfix is available from Microsoft. However, this hotfix is intended to correct only the problem that is described in this article. Apply this hotfix only to systems that are experiencing this specific problem. If the hotfix is available for download, there is a "Hotfix Download Available" section at the top of this Knowledge Base article.

Prerequisites
To apply this hotfix, you must have April 2014 update rollup for Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2 (2919355) installed in Windows 8.1 or Windows Server 2012 R2.
Registry information
To use the hotfix in this package, you do not have to make any changes to the registry.
Restart requirement
You may have to restart the computer after you apply this hotfix.
Hotfix replacement information
This hotfix does not replace a previously released hotfix.
The global version of this hotfix installs files that have the attributes that are listed in the following tables. The dates and the times for these files are listed in Coordinated Universal Time (UTC). The dates and the times for these files on your local computer are displayed in your local time together with your current daylight saving time (DST) bias. Additionally, the dates and the times may change when you perform certain operations on the files.
Windows 8.1 and Windows Server 2012 R2 file information and notes
Important Windows 8.1 hotfixes and Windows Server 2012 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 8.1/Windows Server 2012 R2" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.
-
The files that apply to a specific product, milestone (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:
Version
Product
Milestone
Service branch
6.3.960 0.17 xxx
Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2
RTM
GDR
-
GDR service branches contain only those fixes that are widely released to address widespread, critical issues. LDR service branches contain hotfixes in addition to widely released fixes.
-
The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information" section. MUM, MANIFEST, and the associated security catalog (.cat) files, are very important to maintain the state of the updated components. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
