Hi, I try to add 2 VF functions to VM via network. Livirt networks: vnet0: <network> <name>vnet0</name> <forward mode='hostdev' managed='yes'> <pf dev='eth0'/> </forward> </network>

This is not a good idea to have two NICs sharing the same MAC.
VM can't start because: kvm: -device pci-assign,configfd=24,host=01:10.1,id=hostdev0,bus=pci.0,addr=0x4: Duplicate ID 'hostdev0' for device
libvirt version 1.0.5.
What i am doing wrong?
I guess nothing. Libvirt has generated the same IDs for two devices which is obviously libvirt's faul even in case two NICs sharing the same MAC. Can you post full domain XML (possibly with network XMLs)? I'll try to reproduce and maybe I'll find what's wrong. Michal
