Cumulative Update 2 for System Center 2016 Virtual Machine Manager Technical Preview 5

Scenarios enabled in this cumulative update

Issues that are fixed in this cumulative update

• Issue 1: As a Delegated Administrator (DA), when you try to configure the load balancer on the Network Controller Service, the service crashes with a NULL pointer exception.
  
  This issue is fixed in this cumulative update. However, to temporarily work around this issue, use the Fabric administrator to configure the load balancer.
  
  
• Issue 2: When you try to configure VPN connections that are running on a Network Controller-managed gateway, VMM does not display the VPNServerAddress object on the VMM Console.
  
  If you try to configure a VPN connection from Windows Azure Pack (WAP), the connection fails with an error. This may block users from setting up remote endpoints for the connection.
  
  This issue is fixed in this cumulative update. However, to temporarily work around this issue, you can obtain the VPNServerAddress object from the Network Controller JSON.
  
  
• Issue 3: When you try to configure VPN connections that are running on a Network Controller-managed gateway and specify "IKEV2" as the protocol, the configuration fails, and you receive the following error message:
  Plugin for network service 'Network Controller' threw an exception: 'One or more parameters specified for the operation are not valid. Specify valid parameters.'
  
  Work with the network service vendor to fix the problem.
  
  ID: 50124
  
  This may block Windows Azure Pack (WAP) users from creating Site-to-Site VPN connection with Network Controller fabric. This issue is fixed in this cumulative update. However, to temporarily work around this issue, specify the protocol as "IPsec" (Internet Protocol Security).
• Issue 4: If you configure a Gateway (for NAT) on a Network Controller-managed network without specifying an external address pool (which will be used to configure the external IP address for NAT), configuration of the gateway fails.
  
  
• Issue 5: If the VMM Server is installed on a non-English operating system, deployment of Storage Spaces Direct (S2D) clusters (both aggregated and hyper-converged) through VMM fails.
  
  To work around this issue, use PowerShell to deploy and S2D cluster and to skip cluster validation, as in the following examples.
  
  For an SOFS S2D cluster:
  
  Install-SCStorageFileServer –ClusterName name -ScaleoutFileServerName name -RunAsAccount RunAsAccount -AddExistingComputer Listofnodes -RunAsynchronously -DASModeEnabled –SkipClusterValidation
  
  For a Hyper-converged S2D cluster:
  
  Install-SCVMHostCluster -ClusterName name -JobGroup JobGroup -RunAsynchronously -EnableSpaces -Credential AdminRunAsAccount -VMHost VMHosts –SkipValidation
• Issue 6: Creating Shielded VMs on Guarded Hosts on an untrusted network or on a perimeter network fails.
  
  
• Issue 7: When you deploy the Software Defined Networking (SDN) Gateway and onboard it to the Network Controller in VMM, connectivity issues occur between the gateway VM and the tenant VM.
  
  This issue is fixed in this cumulative update. However, to temporarily work around this issue, disconnect the gateway network adapter, and connect it back to the switch. Or, restart the host.

Known issues

• Logical switch compliance issue with the below error:
  
  Error (26809)
  The virtual switch configuration does not match the expected uplink mode setting of UplinkMode from the logical switch.
  
  Recommended Action
  In VMM, remediate the compliance of this virtual switch on the Hyper-V host.
  
  
• Failure of logical switch deployment

-- TP5 contains SET switches as 'Team' uplink mode with NC managed
-- SET without NC support adds a new 'Embedded Team' uplink mode
-- Convert the uplink mode from 'Team' to 'Embedded Team' for NC managed switches
UPDATE [dbo].[tbl_NetMan_LogicalSwitch]
SET
       UplinkMode = 3 -- Embedded Team
WHERE UplinkMode = 2 AND ID IN (
       -- Find logical switches with MS Azure VFP Extension (MS Network Controller)
       SELECT ls.LogicalSwitchID
       FROM [dbo].[tbl_NetMan_LogicalSwitchToVsemExtension] ls
              INNER JOIN
              [dbo].[tbl_NetMan_VirtualSwitchExtension] vse
              ON ls.VsemExtensionId = vse.ID
       WHERE vse.DriverNetCfgInstanceID = 'E9B59CFA-2BE1-4B21-828F-B6FBDBDDC017' -- Microsoft Azure VFP Extension
       )
