if we assign vif as following, it works with fix-mac.
        # Network devices
        vif = [ 'type=ioemu, mac=00:15:17:19:2D:35, bridge=xenbr0' ]
if we assign VF to guest as following, it till don't have network working with 
fix-mac; after save&restore, the networking status shows as "Network cable 
unplugged", without IP address.
    #SR-IOV VF device BDF
    pci = [ '81:10.1' ]
