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> vnet1: <network> <name>vnet0</name> <forward mode='hostdev' managed='yes'> <pf dev='eth1'/> </forward> </network> In VM configuration: <interface type="network"> <source network="vnet0"/> <mac address="52:54:0a:b1:48:07"/> </interface> <interface type="network"> <source network="vnet1"/> <mac address="52:54:0a:b1:48:07"/> </interface>

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?

Thanks for your response. For two different mac addresses problem is the same.
