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?
