This patch series is based on laines patches to support <interface type='hostdev'>. https://www.redhat.com/archives/libvir-list/2012-February/msg01126.html It support to set mac and port profile on an interface of type hostdev. * If virtualport is specified, the existing virtual port functions are called to set mac, vlan and port profile. * If virtualport is not specified and device is a sriov virtual function, - mac is set using IFLA_VF_MAC * If virtualport is not specified and device is a non-sriov virtual function, - mac is set using existing SIOCGIFHWADDR (This requires that the netdev be present on the host before starting the VM) This series implements the below : 01/4 pci: Add two new pci util pciDeviceGetVirtualFunctionInfo and pciConfigAddressToSysfsFile 02/4 virtnetdev: Add support functions for mac and portprofile associations on a hostdev 03/4 virnetdevvportprofile: Changes to support portprofiles for hostdevs 04/4 qemu_hostdev: Add support to install port profile and mac address on hostdev Stefan Berger is CC'ed for 802.1Qbg changes in patch 03/4. Current code for 802.1Qbg uses macvtap ifname. And for network interfaces with type=hostdev a macvtap ifname does not exist. This patch just adds a null check for ifname in 802.1Qbg port profile handling code. -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
