libvirt users - Nov 2016 - BroadCom NIC not adding as PassThrough device

Hi Guys,

 

I am trying to add a Broadcom Physical NIC to a virtual Machine as
Passthrough device. However I am getting following error.

 

Error starting domain: unsupported configuration: host doesn't support
passthrough of host PCI devices

 

Traceback (most recent call last):

  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 88, in
cb_wrapper

    callback(asyncjob, *args, **kwargs)

  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 124, in
tmpcb

    callback(*args, **kwargs)

  File "/usr/share/virt-manager/virtManager/libvirtobject.py", line
83, in
newfn

    ret = fn(self, *args, **kwargs)

  File "/usr/share/virt-manager/virtManager/domain.py", line 1404, in
startup

    self._backend.create()

  File "/usr/lib64/python2.7/site-packages/libvirt.py", line 1035, in
create

    if ret == -1: raise libvirtError ('virDomainCreate() failed',
dom=self)

libvirtError: unsupported configuration: host doesn't support passthrough of
host PCI devices

 

libvirt allows to appply the changes to the VM xml configurations, but gives
error the moment I try to start the VM.

I have tried following approaches.

 

1- Open Virt-Manager, Shutdown VM, edit VM , add PCI hardware device ,
locate BroadCom NIC, apply changes. Then I restart the VM.

2- Also tried to add following XML tags one by one using 'virsh edit',
but
got same error.

 

Tag -1

<hostdev mode='subsystem' type='pci'
managed='yes'>

  <source>

     <address domain='0x0000' bus='0x02' slot='0x00'
function='0x1'/>

  </source>

</hostdev>

 

Tag -2

   <interface type='hostdev' managed='yes'>

     <source>

       <address type='pci' domain='0x0000' bus='0x02'
slot='0x00'
function='0x1'/>

     </source>

   </interface>

 

The detail of the BroadCOm NIC are as follows.

02:00.1 Ethernet controller: Broadcom Limited NetXtreme II BCM5709 Gigabit
Ethernet (rev 20)

 

 

What would it take to add this NIC to VM as Passthrough Device?

Hi,

does your host support the passthrough (I/O MMU virtualization: i.e.
VT-d for Intel, AMD-Vi for AMD CPUs)? Is it enabled in BIOS and kernel?
