New with Linux Integration Services 4.1:
•Expanded Releases: now applicable to Red Hat Enterprise Linux, CentOS, and Oracle Linux with Red Hat Compatible Kernel versions 5.2, 5.3, 5.4, and 7.2.
•Manual Memory Hot Add.
When installed in a supported Linux virtual machine running on Hyper-V, the Linux Integration Services provide:
•Driver support: Linux Integration Services supports the network controller and the IDE and SCSI storage controllers that were developed specifically for Hyper-V.
•Fastpath Boot Support for Hyper-V: Boot devices now take advantage of the block Virtualization Service Client (VSC) to provide enhanced performance.
•Time Keeping: The clock inside the virtual machine will remain accurate by synchronizing to the clock on the virtualization server via Timesync service, and with the help of the pluggable time source device.
•Integrated Shutdown: Virtual machines running Linux can be shut down from either Hyper-V Manager or System Center Virtual Machine Manager by using the “Shut down” command.
•Symmetric Multi-Processing (SMP) Support: Supported Linux distributions can use multiple virtual processors per virtual machine. The actual number of virtual processors that can be allocated to a virtual machine is only limited by the underlying hypervisor.
•Heartbeat: This feature allows the virtualization server to detect whether the virtual machine is running and responsive.
•KVP (Key Value Pair) Exchange: Information about the running Linux virtual machine can be obtained by using the Key Value Pair exchange functionality on the Windows Server 2008 virtualization server.
•Integrated Mouse Support: Linux Integration Services provides full mouse support for Linux guest virtual machines.

In New VMM 2012 R2 with CU3 implementation when you try to add VM to existing user role you may see below error
VMM encountered a critical exception and created an exception report at C:\ProgramData\VMMLogs\SCVMM.4e32da1c-645d-42b3-8c79-612d502ca2ff\report.txt.
See the report for more details and search user forums for well-known failure root causes for self-help.
After some investigation I found the error related to VMM DB, After applying the CU3 you need to run same SQL script described in CU1, CU2
Important After you install the update package, you must apply the following SQL script on your Virtual Machine Manager Microsoft SQL Server database for Update Rollup 2 to function correctly.
Please make sure to have a backup from VMM DB before any modification to it. Once script run successfully the VM can be added to user role without any issue
Sometimes when you check the event viewer for Service Manager “Operations Manager” you get event ID 33880
A Windows Workflow Foundation workflow failed during execution.
Workflow Type: Microsoft.EnterpriseManagement.ServiceManager.SLA.Workflows.ApplySLAOnGroupInstance
Workflow Identifier: b3c0e6b3-b14e-345b-0cdc-cb6feaa9e3cd
Exception Type: Microsoft.EnterpriseManagement.Common.InconsistentDataException
Exception Message: Could not retrieve SLO information from the system. This can happen when SLO was either deleted or not created through console.
Exception Stack: at Microsoft.EnterpriseManagement.ServiceManager.SLA.Workflows.ApplySLAOnGroupInstance.ApplySLA_ExecuteCode(Object sender, EventArgs e)
at System.Workflow.ComponentModel.Activity.RaiseEvent(DependencyProperty dependencyEvent, Object sender, EventArgs e)
at System.Workflow.Activities.CodeActivity.Execute(ActivityExecutionContext executionContext)
at System.Workflow.ComponentModel.ActivityExecutor`1.Execute(T activity, ActivityExecutionContext executionContext)
at System.Workflow.ComponentModel.ActivityExecutorOperation.Run(IWorkflowCoreRuntime workflowCoreRuntime)
This happens due to missing Workflow in one of the management packs, To correct that you have to get the workflow and remove it
to get the workflow using identifier you can open SM powershell and run
get-scsmworkflow -id <WorkflowID>
if the workflow does not exist in the SM console or if you would like to force deleting it then run:
get-scsmworkflow -id <WorkflowID> | remove-scsmworkflow
Hyper-V supports both emulated (“legacy”) and Hyper-V-specific (“synthetic”) devices for Linux virtual machines. When a Linux virtual machine is running with emulated devices, no additional software is required to be installed. However, emulated devices do not provide high performance and cannot leverage the rich virtual machine management infrastructure that the Hyper-V technology offers. To make full use of all benefits that Hyper-V provides, it is best to use Hyper-Vspecific devices for Linux. The collection of drivers that are required to run Hyper-V-specific devices is known as Linux Integration Services (LIS).
For certain older Linux distributions, Microsoft provides an ISO file containing installable LIS drivers for Linux virtual machines. For newer Linux distributions, LIS is built into the Linux operating system, and no separate download or installation is required. This guide discusses the installation and functionality of LIS drivers on older Linux distributions.
Blow are the main Points that comes with version 3.5
New OS with 3.5
Expands the list of supported distributions to include RHEL/CentOS 5.5-5.6.
Supported Virtualization Server Operating Systems
This version of Linux Integration Services (LIS) supports the following versions of Hyper-V:
Windows Server 2008 R2 Standard, Windows Server 2008 R2 Enterprise, and Windows Server 2008 R2 Datacenter
Microsoft Hyper-V Server 2008 R2
Windows 8 Pro
Windows 8.1 Pro
Windows Server 2012
Windows Server 2012 R2
Microsoft Hyper-V Server 2012
Microsoft Hyper-V Server 2012 R2
When installed on a virtual machine that is running a supported Linux distribution, LIS 3.5 for Hyper-V provides the functionality listed in the table below. For comparative purposes, hereunder also list the features available in LIS 3.4. This allows users to decide if they want to upgrade from LIS 3.4 to LIS 3.5.
1. Static IP injection might not work if Network Manager has been configured for a given HyperV-specific network adapter on the virtual machine. To ensure smooth functioning of static IP injection, ensure that either Network Manager is turned off completely, or has been turned off for a specific network adapter through its Ifcfg-ethX file.
2. When you use Virtual Fibre Channel devices, ensure that logical unit number 0 (LUN 0) has been populated. If LUN 0 has not been populated, a Linux virtual machine might not be able to mount Virtual Fibre Channel devices natively.
3. If there are open file handles during a live virtual machine backup operation, the backed-up virtual hard disks (VHDs) might have to undergo a file system consistency check (fsck) when restored.
4. Live backup operations can fail silently if the virtual machine has an attached iSC SI device or a physical disk that is directly attached to a virtual machine (“pass-through disk”).
5. LIS 3.5 only provides Dynamic Memory ballooning support—it does not provide hot-add support. In such a scenario, the Dynamic Memory feature can be used by setting the Startup memory parameter to a value which is equal to the Maximum memory parameter. This results in all the requisite memory being allocated to the virtual machine at boot time—and then later, depending upon the memory requirements of the host, Hyper-V can freely reclaim any memory from the guest. Also, ensure that Startup Memory and Minimum Memory are not configured below distribution recommended values.

The System Center Configuration Manager Company Portal app allows users of Windows 8 and Windows 8.1 machines to view and install applications made available to the user by their administrators. The machine must be managed by Microsoft System Center 2012 R2 Configuration Manager, or later, with the agent installed.
The app communicates directly with the Configuration Manager on-premise server infrastructure. Note that this contrasts with the Windows Intune Company Portal app (available through the Windows Store and the Download Center) which communicates directly with the Windows Intune service.
- System Center 2012 R2 Configuration Manager
- The Application Catalog Web Service and Application Catalog Website Point roles must be operational on one or more primary sites
- End User Machines
- Windows 8 Pro, Windows 8 Enterprise, Windows 8.1 Pro or Windows 8.1 Enterprise
- Machine must be domain-joined
- System Center 2012 R2 Configuration Manager (or later) client agent must be installed
- User must be logged on with domain credentials
To enable Company Portal app functionality a registry key must be present on target devices. This allows the Configuration Manager agent to communicate with the Company Portal app. The required value is:
- Key = [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\CCM]
- Value Name = PortalPackageFamily
- Type = REG_SZ
- Value = Microsoft.CorporateAppCenter_8wekyb3d8bbwe
To deploy the Company Portal app, use the following steps:
- Ensure that the Application Catalog role is operational on one or more primary sites. For more information, refer to the following TechNet article: Configuring the Application Catalog and Software Center in Configuration Manager (http://go.microsoft.com/fwlink/?LinkID=247211).
- Deploy the registry value specified above to all clients on which the Company Portal app will be installed. This can be done via Group Policy, the Compliance Settings feature of Configuration Manager, or any other method applicable in your organization.
- Deploy the Company Portal app. You can deploy this app to Windows 8 or Windows 8.1 workstations through the Application Management feature. For more information, refer to the following TechNet article: Introduction to Application Management in Configuration Manager (http://go.microsoft.com/fwlink/?LinkID=247184) and select “Windows app package (*.appx, *.appxbundle)” in the Create Application wizard.
Note: The Company Portal app may take up to 15 minutes after installation before it is fully operational
Recommendations and Best Practices
Consider the following when deploying the Company Portal app in your environment.
- The Company Portal app utilizes the default Application Catalog Website Point assigned to the device when communicating with the Configuration Manager infrastructure. For more information, refer to the following TechNet article: About Client Settings in Configuration Manager (http://go.microsoft.com/fwlink/?LinkID=252184).
- If you have multiple primary sites in a hierarchy, we strongly recommend adding a set of Application Catalog roles for each of the primary sites, and using Automatic detection to control the default Application Catalog Website Points.
- When the user browses the list of applications in the Company Portal, the app will display the applications that have been made available to the user, similar to the Configuration Manager Application Catalog functionality. The Company Portal will assess the operating system requirements specified for the deployment type of the application to determine if the application should be available for installation.
