Windows Server 2012R2 with Hyper-V and UCS SCVMM problems

Hello,

I am following the guide available at

http://www.cisco.com/en/US/docs/unified_computing/ucs/sw/vm_fex/hyperv/gui/config_guide/2.2/b_GUI_Hyper-V_VM-FEX_UCSM_Configuration_Guide_2_2_1_chapter_0100.html

I am on section

Creating a VM in      SCVMM

But when I try to attach a nic to a VM to:

VM Network: UCS-SCVMM

VM Subnet Vlan-70

Logical Switch UCS-SCVMM

Classification: SR-IOV

I receive the following errors:

Error (12700)

VMM cannot complete the host operation on the (Blanked for security) server because of the error: 'UCS-TEST' failed to modify device 'Ethernet Connection'. (Virtual machine ID A76B1330-B91D-42D7-BE0C-C6EFF23528E2)

Failed while applying switch port settings 'Ethernet Switch Port VLAN Settings' on switch 'UCS-SCVMM': The request is not supported. (0x80070032).

Unknown error (0x8000)

Recommended Action

Resolve the host issue and then try the operation again.

Error (25262)

Cannot set a bandwidth setting on the virtual network adapter for the SR-IOV switch (UCS-SCVMM).

Recommended Action

Check the Hyper-V virtual port profile and correct the issue, and then try again.

Does anyone have any insight into this? Has anyone successfully deployed UCS SCVMM extension on Server 2012R2?

How does your service profile look like ? e.g. static, dynamic vnic's ?

Re: Windows Server 2012R2 with Hyper-V and UCS SCVMM problems

I've attached a zip file with screen caps and XML's from the service profile

There are 3 NICS

2 static nics

1 Vnic with a dynamic policy which is bound to the SCVMM Switch (vNIC_PF_Vnic1)

This is the Vnic that should be utilized by SCVMM on this host.

Re: Windows Server 2012R2 with Hyper-V and UCS SCVMM problems

Q.

- is there a single vlan or a trunk attaching the vswitch

- I would remove the pin-group from the port-profile

- which vlan is specified in the port-profile ? native ?

- in the port profile: Host Network IO Performance = High Performance

It seems, that the vlan of the SR-IOV needs to be native !

The PF Vnic within UCS Manager has one vlan attached and is tagged native. The Fabric Network Set has a matching network segment with the same vlan ID. I removed the pin group. The port profile according to the SCVMM documentation needs to be set to "Sla only" which removes the options for vlans within the port profile. I've tried adjusting Host Network IO Performance as well with no luck. System Center Virtual Machine Manager 2012R2 still throws the same two errors. One thing to note is we are trying to do this thru SCVMM and not Hyper-V on the host itself.

I opened a TAC case and there is one known bug for

Symptom:

Everytime I assign a Logical Switch to a network adapter or during migration, SCVMM generate an error 25262, "Cannot set a bandwidth setting on the virtual network adapter for the SR-IOV switc

Conditions:

[ From SCVMM, right click VM and assign logical switch to a network adapter.

OR

Migrate a client to a different host.

There is no workaround for the issue currently.

My other issue of

Failed while applying switch port settings 'Ethernet Switch Port VLAN Settings' on switch 'UCS-SCVMM': The request is not supported. (0x80070032).

Unknown error (0x8000) has no fix or information.
